Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol rate more than 3000000 and delay of 3000ms less than this. Adding min delay prevents crashing the frontend on continuous transponder scans. Other dvb_frontend_tune_settings remain as default. This makes very little time difference to good channel scans, but slows down the set frontend where lock can never be achieved i.e. DVB-S2.

The error checking code relative to the invocations of kinect_read() does not return the actual return code of the function just called, it returns "res" which still contains the value of the last invocation of a previous kinect_write(). Return the proper value, and while at it also report with -EREMOTEIO the case of a partial transfer.

sleep_on and its variants are broken and going away soon. This changes the omap vout driver to use wait_event_interruptible_timeout instead, which fixes potential race where the dma is complete before we schedule.

interruptible_sleep_on is racy and going away. This replaces one use in the radio-cadet driver with a wait_event_interruptible call. Special care was taken that accesses to the rdsin and rdsout indices are always done with dev->lock held.

The queue_setup handler takes an optional format argument that can be used to allocate buffers for a format different than the current format. The uvcvideo driver doesn't support changing the format when buffers have been allocated, but there's no reason not to support allocating buffers larger than the minimum size. When the format argument isn't NULL verify that the requested image size is large enough for the current format and use it for the buffer size.

Thomas Pugliese authored
Isochronous endpoints on devices with speed == USB_SPEED_WIRELESS can have a max packet size ranging from 1-3584 bytes. Add a case to uvc_endpoint_max_bpi to handle USB_SPEED_WIRELESS. Otherwise endpoints for those devices will fall to the default case which masks off any values > 2047. This causes uvc_init_video to underestimate the bandwidth available and fail to find a suitable alt setting for high bandwidth video streams.
