[media] rtl28xxu: fix control message flaws

2015-10-22T17:48:27+00:00

Add lock to prevent concurrent access for control message as control
message function uses shared buffer. Without the lock there may be
remote control polling which messes the buffer causing IO errors.
Increase buffer size and add check for maximum supported message
length.

[media] cx231xx: Use wake_up_interruptible() instead of wake_up_interruptible_nr()

2015-09-03T16:50:52+00:00

While looking at use cases of the wake queues in order to add support
for simple wait queues, I noticed that there was only a single user of
wake_up_interruptible_nr(), and that use was doing a single task wake
up. Have that user use the proper wake_up_interruptible() instead, and
perhaps we can even remove the function wake_up_interruptible_nr().

[media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices

2015-08-11T17:43:23+00:00

Using 8 URBs results in a consecutive buffer allocation of too much
memory for some arm devices.
As we use isochronuous transfers the number of URBs can be reduced
without risking data-loss.

[media] Drop owner assignment from i2c_driver

2015-08-11T16:01:57+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

[media] pctv452e: Replace memset with eth_zero_addr

2015-08-11T15:57:01+00:00

Use eth_zero_addr to assign the zero address to the given address
array instead of memset when second argument is address of zero.
Note that the 6 in the third argument of memset appears to represent
an ethernet address size (ETH_ALEN).

The Coccinelle semantic patch that makes this change is as follows:

// 
@eth_zero_addr@
expression e;
@@

-memset(e,0x00,6);
+eth_zero_addr(e);
//

[media] em28xx: remove unused a8293 SEC config

2015-08-11T10:08:01+00:00

Devices that were using a8293 SEC are converted to I2C platform data
thus that old config structure is left unused.

[media] usbvision: move init code to probe()

2015-08-11T09:55:26+00:00

These things are only initialized if you start streaming video, but
they are also used in the disconnect function. So just init them
always during probe time.

In various places the stack was used to provide buffers for USB data, but
this should be allocated memory.
