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.

(Resending because Mauro reported losing some emails on IRC) Provide CX2388[578] IR receive timeout (RTO) reports in the final space raw event sent up the chain to the raw IR pulse decoders. This should allow the lirc decoder to actually measure the inter-transmission gap properly. Signed-off-by:

Switch to generic media bus signal polarity flags and allow configuring the FIELD signal polarity. Signed-off-by:

Sylwester Nawrocki authored
FIELD signal is used for indicating frame field type to the frame grabber in interlaced scan mode, as specified in ITU-R BT.601 standard. In normal operation mode FIELD = 0 selects Field1 (odd) and FIELD = 1 selects Field2 (even). When the FIELD signal is inverted it's the other way around. Add corresponding flags for configuring the FIELD signal polarity, V4L2_MBUS_FIELD_EVEN_HIGH for the standard (non-inverted) case and V4L2_MBUS_FIELD_EVEN_LOW for inverted case. Also add a comment about usage of V4L2_MBUS_[HV]SYNC* flags for the hardware that uses [HV]REF signals. Signed-off-by:

This patch is adapted from a patch from Sarah Sharp (2010/05/03). The xHCD handler checks the USB bandwidth on usb_set_interface() instead of on usb_submit_urb(). Now, the same treatment is applied in case of error of both functions. Signed-off-by:

This is an improved version of the patch I sent a little ago. The problem was: On my DC-1125 webcam chip from Syntek, whenever the webcam turns on, the LED light on it is turned on also and never turns off again unless system is shut downed or restarted. The previous version seemed to break some other laptop webcam work. Thanks to Andrea Anacleto for the bug report and solution. Signed-off-by:

The UVC driver uses usb_alloc_coherent() to allocate DMA data buffers. On systems without coherent DMA this ends up allocating buffers in uncached memory. The subsequent memcpy's done to coalesce the DMA chunks into contiguous buffers then run VERY slowly. On a MIPS test system the memcpy is about 200 times slower. This issue prevents the system from keeping up with 720p YUYV data at 10fps. The following patch uses kmalloc to alloc the DMA buffers instead of usb_alloc_coherent on systems without coherent DMA. With this patch the system was easily able to keep up with 720p at 10fps. Signed-off-by:

The ati_remote_dump() function tries to not print "Weird byte" warning for 1-byte responses that contain 0xff or 0x00, but it doesn't work properly as it simply falls back to the "Weird data" warning in the else clause. Fix that by adding an inner if clause. Signed-off-by:
