2012-12-22[media] em28xx: fix wrong data offset for non-interlaced mode in ↵Frank Schaefer
em28xx_copy_video em28xx_copy_video uses a wrong offset for the target buffer when copying the data from an USB isoc packet. This happens only for the second and all following lines in the packet. The reason why this bug doesn't cause image corruption with my test device (SilverCrest Webcam 1.3 MPix) is, that this device never sends any packets that cross the end of a line. I don't know if all devices behave like this, so this patch should be considered for stable. With the upcoming patches to add support for USB bulk transfers, em28xx_copy_video will be called once per URB, which will always trigger this bug.

2012-12-22[media] em28xx: input: fix oops on device removalFrank Schaefer
When em28xx_ir_init() fails due to an configuration error, it frees the memory of struct em28xx_IR *ir, but doesn't set the corresponding pointer in the device struct to NULL. On device removal, em28xx_ir_fini() gets called, which then calls rc_unregister_device() with a pointer to freed memory.

2012-12-21[media] em28xx: add support for RC6 mode 0 on devices that support itMauro Carvalho Chehab
Newer em28xx chipsets (em2874 and upper) are capable of supporting RC6 codes, on both mode 0 (command mode, 16 bits payload size, similar to RC5, also called "Philips mode") and mode 6a (OEM command mode, with offers a few alternatives with regards to the payload size). I don't have any mode 6a control ATM to test it, so, I opted to add support only to mode 0. After this patch, adding support to mode 6a should not be hard. Tested with a Philips television remote controller. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-12-21[media] em28xx: add support for NEC proto variants on em2874 and upperMauro Carvalho Chehab
By disabling the NEC parity check, it is possible to handle all 3 NEC protocol variants (32, 24 or 16 bits). Change the driver in order to handle all of them. Unfortunately, em2860/em2863 provide only 16 bits for the IR scancode, even when NEC parity is disabled. So, this change should affect only em2874 and newer devices, with provides up to 32 bits for the scancode. Tested with one NEC-16, one NEC-24 and one RC5 IR.

The stk-webcam module is inserted upside-down in some webcams, so we need to de hflip and vflip by default on some models. Note that this patch inverts the value of the controls as reported by the control API in this case so that for the user they still make sense (iow not doing any flipping from the ctrl API pov results in an upright image).

2012-12-17[media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2Michael Krufky
This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.
