The card definition of the Terratec Cinergy 200 USB uses the
wrong tuner type. Therefore some channels are currently missing.
Attached patch fixes this problem.

The MaxPacketSize for em2800 based devices is too small to capture at full resolution.
Therefore scale down when the maximum frame size is selected.
The previous workaround that simply reduced the X resolution cannot be used
because it crops a part of the input as
the em2800 can only scale down with a factor of 0.5.
reverts commits 1ca31892e and fb3de0398ab.

writing the EM28XX_R06_I2C_CLK register leads to the problem that the
i2c bus on the Terratec Cinergy 200 USB is no longer usable when the
system is rebooted.
The device needs to be unplugged in order to bring it back to life.
Attached patch conditionally disables the write in
em28xx_pre_card_setup() like it is already done in em28xx_card_setup().

Adds support for the Plextor ConvertX PX-AV100U, which uses the
eMPIA EM2820 chip. The device has a device_id of '0x093b, 0xa003'. I
am using the existing EM2820_BOARD_PINNACLE_DVC_90 board profile, as
the Pinnacle Dazzle DVC 90/100/101/107, Kaiser Baas Video to DVD
maker, and Kworld DVD Maker 2 were already mapped to it. Some more
background on the device and my testing can be found at

This converts the drivers in drivers/media/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

Pidgin uses gstreamer (and libv4l) to work. Without implementing this ioctl,
it won't detect properly the size range, and driver will fail.
So, this patch is required, in order to use an em27xx webcam, like
Silvercrest.
The pigdin/gstreamer/libv4l needs to be fixed, as it shouldn't assume
that all drivers will implement this optional ioctl, but, at least now,
devices with em28xx have a better chance of working with pidgin.

Simplifies the locking by moving the em28xx_init_extension() call until
em28xx_usb_probe() has finished with the dev->lock mutex. It therefore
makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules
must be loaded (i.e. registered).
Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and
also triggers udev to initialise the V4L2 devices. These two events are
serialised by the dev->lock mutex but the order that they happen in is
undefined. But this has always been the case anyway.

This fixes the deadlock that occurs with either multiple PCTV 290e adapters or when a single PCTV 290e adapter is replugged.
For DVB devices, the device lock must now *not* be held when adding/removing either a device or an extension to the respective lists. (Because em28xx_init_dvb() will want to take the lock instead).
Conversely, for Audio-Only devices, the device lock *must* be held when adding/removing either a device or an extension to the respective lists.

This patch closes the race on the device and extension lists at USB disconnect
time. Previously, the device was removed from the device list during
em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. However, this
left a (brief, theoretical, highly unlikely ;-)) window between these two calls
during which a new module could call em28xx_register_extension(). The result
would have been that the em28xx_usb_disconnect() function would also have passed
the device to the new extension's fini() function, despite never having called
the extension's init() function.
This patch also restores em28xx_close_extension()'s symmetry with
em28xx_init_extension(), and establishes the property that every device in the
device list must have been initialised for every extension in the extension list.

The DVB framework will try to power-down an adapter that no-one is using
any more, but this assumes that the adapter is still connected to the
machine. That's not always true for a USB adapter, so disable the sleep
operations when the adapter has been physically unplugged.
This prevents I2C write failures with error -19 from appearing
occasionally in the dmesg log.

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert
Schlabbach for identifying the register address and field to set.
The old i2c intercept code that prefixed messages with a passthrough byte has
been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been
updated appropriately.
Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities
could test it as well - from inspection I cannot see any problems.
This is patch v2. It fixes some schoolboy style errors and removes superfluous
i2c entries in cxd2820r.h.

The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.
Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.
For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

Both ngene and ddbrige calls dvb_attach once for drxk_attach.
The logic used there, and by tda18271c2dd driver is different
from similar logic on other frontends.
The right fix is to change them to use the same logic, but,
while we don't do that, we need to patch em28xx-dvb in order
to do cope with ngene/ddbridge magic.
While here, document why drxk_t_release should do nothing.
