commit 19f48cb105b7fa18d0dcab435919a3a29b7a7c4c upstream.
this patch fixes a memory leak which occurs when an em28xx card with DVB
extension is unplugged or its DVB extension driver is unloaded. In
dvb_fini(), dev->dvb must be freed before being set to NULL, as is done
in dvb_init() in case of error.
Note that this bug is also present in the latest stable kernel release.

waiting processes
commit 1f95725755ab67f3198df3b5bf7517f926f310ca upstream.
The s2255 driver had logic which aborted processing of a video frame
if there was no process waiting on the video buffer in question. That
simply doesn't work when the application is doing things in an
asynchronous manner. If the application went to the trouble to queue
the buffer in the first place, then the driver should always attempt
to complete it - even if the application at that moment has its
attention turned elsewhere. Applications which always blocked waiting
for I/O on the capture device would not have been affected by this.
Applications which *mostly* blocked waiting for I/O on the capture
device probably only would have been somewhat affected (frame lossage,
at a rate which goes up as the application blocks less). Applications
which never blocked on the capture device (e.g. polling only) however
would never have been able to receive any video frames, since in that
case this "is anyone waiting on this?" check on the buffer never would
have evalutated true. This patch just deletes that harmful check
against the buffer's wait queue.

commit 96fbf771d86a90ff006bc62ca4d4de6474b3de31 upstream.
Because the counters were not reset when starting up streaming, they would
be reused from the previous run. This can result in cases such that when the
second instance of streaming starts up, the "cnt" variable in
em28xx_audio_isocirq() can end up being negative, resulting in attempting to
write to memory before the start of runtime->dma_area (as well as having a
negative number of bytes to copy).

tda18271_rf_tracking_filters_init
commit a57c1dcb93e43357ed3f666e5a2b5d5071dd3930 upstream.
While having tda18271 module set with debug=17 (cal & info prints) and
cal=0 (delay calibration process until first use) - I discovered that
during the calibration process, if the frequency test for 69750000
returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that
the tuner wouldn't be able to pickup any of the frequencies in the range
(all the other frequencies bands returned bcal=1). I spent some time
going over the code and the NXP's tda18271 spec (ver.4 of it i think) and
adding a lot of debug prints and walking/stepping through the calibration
process. I found that when the powerscan fails to find a frequency, the
rf calibration is not run and the default value is supposed to be used in
its place (pulled from the RF_CAL_map table) - but something was getting
goofed up there.
Now, my c coding skills are very rusty, but i think root of the problem is
a signedness issue with the math operation for calculating the rf_a1 and
rf_a2 values in tda18271_rf_tracking_filters_init func, which results in
values like 20648 for rf_a1 (when it should probably have a value like 0,
or so slightly negative that it should be zero - this bad value for rf_a1
would in turn makes the approx calc within
tda18271c2_rf_tracking_filters_correction go out of whack). The simplest
solution i found was to explicitly convert the signedness of the
denominator to avoid the implicit conversion. The values placed into the
u32 rf_freq array should never exceed about 900mhz, so i think the s32 max
value shouldn't be an issue in this case.
I've tested it out a little, and even when i get a bcal=0 with the
modified code, the default calibration value gets used, rf_a1 is zero, and
the tuner seems to lock on the stream and mythtv seems to play it fine.

commit 4d8317876d5f53ef792e90f89d8f162d7bca5c81 upstream.
Multiplication by 62500 causes an overflow in the 32 bit freq variable,
which is later divided by 1000 when using FM radio.
This patch prevents the overflow by scaling the frequency value correctly
upfront. Thanks to Henk Vergonet for spotting the problem and providing
a preliminary patch, which this changeset was based upon.

commit 7646b9de26c54cf4bc9c446d7ada9f91ece31e0a upstream.
Fixing kernel oops when driver attemps to load xc2028 firmware.
Note by djh: the patch contribute by Martin is a port of a fix I made during
the PCTV 340e development. It's a temporary workaround that fixes a regression
(an OOPS condition) and the real fix should be in the code that manages the
i2c master on the dib7000p. But this fix does address the immmediate
regression and should be merged upstream until we do a cleaner fix.

only cards
commit cd8f894eacf13996d920fdd2aef1afc55156b191 upstream.
Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.
Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.
This causes a NULL error to show up in video_open and mpeg_open.
-Mark
Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

(cherry picked from commit ac9575f75c52bcb455120f8c43376b556acba048)
The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug
causing decoder commands to crash. The decoder commands should have been
handled from the video_ioctl2 default handler, ensuring correct mapping
of the argument between user and kernel space. Unfortunately they ended
up before the video_ioctl2 call, causing random crashes.
Thanks to hannes@linus.priv.at for testing and helping me track down the
cause!

(cherry picked from commit 67e70baf043cfdcdaf5972bc94be82632071536b)
Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it
to know that the tuner has been told to change frequencies. This change
changes the behavior from "random tuning times between 500ms to complete
tuning lock failures" to "tuning lock consistently within 700ms".

commit 01a1a3cc1e3fbe718bd06a2a5d4d1a2d0fb4d7d9 upstream.
This bug were supposed to be fixed by 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1,
where a call to NULL happens.
Not all tvaudio chips allow controlling bass/treble. So, the driver
has a table with a flag to indicate if the chip does support it.
Unfortunately, the handling of this logic were broken for a very long
time (probably since the first module version). Due to that, an OOPS
were generated for devices that don't support bass/treble.
This were the resulting OOPS message before the patch, with debug messages
enabled:

commit c82732a42896364296599b0f73f01c5e3fd781ae upstream
Fix deadlock problem in 2.6.27 caused by new USB core behavior in
response to a USB device reset request. With older kernels, the USB
device reset was "in line"; the reset simply took place and the driver
retained its association with the hardware. However now this reset
triggers a disconnect, and worse still the disconnect callback happens
in the context of the caller who asked for the device reset. This
results in an attempt by the pvrusb2 driver to recursively take a
mutex it already has, which deadlocks the driver's worker thread.
(Even if the disconnect callback were to happen on a different thread
we'd still have problems however - because while the driver should
survive and correctly disconnect / reconnect, it will then trigger
another device reset during the repeated initialization, which will
then cause another disconect, etc, forever.) The fix here is simply
to not attempt the device reset (it was of marginal value anyway).

Correct firmware type to MTS
Correct audio routing for composite/s-video
Add DVB-T detection.
This patch uses the eeprom hash method for detection as the vendor/product
ids are also used for the DIGIVOX_AD. This may be a clone of the same
product. Explanatory text has been added prior to the hask look-up in
anticipation that it may help others.
The following has been tested to work:
Analogue TV (PAL-I)
Composite In
DVB-T (UK Crystal Palace)
USB AUDIO
The following has not been tested but probably works:
S-Video In

There is a buffer overflow in drivers/media/video/uvc/uvc_ctrl.c:
INFO: 0xf2c5ce08-0xf2c5ce0b. First byte 0xa1 instead of 0xcc
INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975
...
A fixed size 8-byte buffer is allocated, and a variable size field is read
into it; there is no particular bound on the size of the field (it is
dependent on hardware and configuration) and it can overflow [also
verified by inserting printk's.]
The patch attempts to size the buffer to the correctly.

Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.
Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.
This patch needs to go into the current release of the kernel, as this driver
is currently broken.
(Thanks to Eberhard Kaltenhaeuser for helping out to debug this issue.)

The functions dvb_dmxdev_section_callback, dvb_dmxdev_ts_callback,
dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and
dvb_dmx_swfilter_204 may be called from both interrupt and process
context. Therefore they need to be protected by spin_lock_irqsave()
instead of spin_lock().
This fixes a deadlock discovered by lockdep.

The zr36067 driver should return the actual bytes-per-line value when
queried with ioctl VIDIOC_G_FMT, instead of 0. Otherwise user-space
applications can get confused.
Likewise, with ioctl VIDIOC_S_FMT, we are supposed to fill the
bytes-per-line value. And we shouldn't fail if the caller sets the
initial value to something different from 0. This is perfectly valid
for applications to pre-fill this field with the value they expect.

Fix the following crash in the bttv driver:
BUG: unable to handle kernel NULL pointer dereference at 000000000000036c
IP: [<ffffffffa037860a>] radio_open+0x3a/0x170 [bttv]
This happens because radio_open assumes that all present bttv devices
have a radio function. If a bttv device without radio and one with
radio are installed on the same system, and the one without radio is
registered first, then radio_open checks for the radio device number
of a bttv device that has no radio function, and this breaks. All we
have to do to fix it is to skip bttv devices without a radio function.
