The problem may occur with SMP: - a frame is completed at interrupt level (in gspca_frame_add with packet_type == LAST_PACKET, - just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting the bit V4L2_BUF_FLAG_DONE, on the other processor, the application tries to requeue the same frame buffer, - then, the qbuf function succeeds because ALL_FLAGS are not set. The fix sets and resets the two flags in one instruction.

Since commit b4028437 the 'driver_data' field resides in device's struct device_private which may be allocated by dev_set_drvdata() if device_private struct was not allocated previously. dev_set_drvdata() is used in video_set_drvdata() to set the driver's private data pointer in v4l2 drivers. Setting the private data _before_ registering the v4l2 device results in a memory leak since __video_register_device() also calls video_set_drvdata(), but after zeroing the device structure. Thus, the reference to the previously allocated device_private struct goes lost and a new device_private will be allocated. All v4l drivers which call video_set_drvdata() _before_ calling video_register_device() are affected. The patch fixes __video_register_device() to preserve previously allocated device_private reference. Caught by kmemleak.

The UVCIOC_CTRL_MAP ioctl doesn't support menu entries for menu controls. As the uvc_xu_control_mapping structure has no reserved fields, this can't be fixed while keeping ABI compatibility. Modify the UVCIOC_CTRL_MAP ioctl to add menu entries support, and define UVCIOC_CTRL_MAP_OLD that supports the old ABI without any ability to add menu controls.

According to the v4l2 spec, writing any value to a button control should result in the action belonging to the button control being triggered. UVC cams however want to see a 1 written, this patch fixes this by overriding whatever value user space passed in with -1 (0xffffffff) when the control is a button control.

It might be useful to be able to disable the IR support, either for debugging purposes, or just for users who know they won't use the IR remote control anyway. On many cards, IR support requires expensive polling/sampling which is better avoided if never needed.

Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization. This is the same as was done for the bttv driver several months ago. Might solve bugs which have not yet been reported for some cards. It makes both drivers consistent, and makes it easier to disable IR support (coming soon.)

Convert the cx23885 driver to use the new in kernel IR pulse decoders for the integrated CX2388[578] IR controllers.

Move from the generic, shared card_ir state structure to a cx23885 driver specific IR state structure in anticipation of moving to the new IR pulse decoders in the IR core.
