em28xx usb driver will have to suspend and resume its extensions. Adding suspend and resume to em28xx_ops gives extensions the ability to install suspend and resume that can be invoked from em28xx_usb driver suspend() and resume() interfaces. Approach: Add power management support to em28xx usb driver. This driver works in conjunction with extensions for each of the functions on the USB device for video/audio/dvb/remote functionality that is present on media USB devices it supports. During suspend and resume each of these extensions will have to do their part in suspending the components they control. Adding suspend and resume hooks to the existing struct em28xx_ops will enable the extensions the ability to implement suspend and resume hooks to be called from em28xx driver. The overall approach is as follows: -- add suspend and resume hooks to em28xx_ops -- add suspend and resume routines to em28xx-core to invoke suspend and resume hooks for all registered extensions. -- change em28xx dvb, audio, input, and video extensions to implement em28xx_ops: suspend and resume hooks. These hooks do what is necessary to suspend and resume the devices they control. Signed-off-by:

Restructure the way we bring the various GPIOs out of reset. In particular: 1. we only need to setup the GPIOs as outputs once 2. there's no point in writing 0x40 to register 0x00 since that's the EEPROM write protect and already it's configured as an input 3. Separate out the act of enabling the power supply and bringing the tuner and demod out of reset. If you don't then the chip may not be properly enabled (as the power supply is still ramping up when the chip comes out of reset). This can result in probing failures.

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. Signed-off-by:

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. Reported-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
