2015-04-08[media] vivid: add support to set CVT, GTF timingsPrashant Laddha
In addition to v4l2_find_dv_timings_cap(), where timings are searched against the list of preset timings, the incoming timing from v4l2-ctl is checked against CVT and GTF standards. If it confirms to be CVT or GTF, it is treated as valid timing and vivid format is updated with new timings.

2015-04-08[media] vivid: add CVT,GTF standards to vivid dv timings capsPrashant Laddha
Currently vivid supports V4L2_DV_BT_STD_DMT and V4L2_DV_BT_STD_CEA861 discrete video standards. Extending the capability set to allow for setting CVT and GTF standards. This change, along with adding the support for calculating CVT, GTF timings in v4l2-ctl would extend the number of resolutions supported by vivid to almost any custom resolution. Also extending the limits on min and max pixel clock to accommodate pixel clock range provided by cvt/gtf for resolutions ranging from 640x360p50 to 4kx2Kp60.

2015-04-08[media] sur40: fix occasional hard freeze due to buffer queue underrunFlorian Echtler
This patch fixes a kernel panic which occurs when buf_list is empty. This can happen occasionally when user space is under heavy load (e.g. due to image processing on the CPU) and new buffers aren't re-queued fast enough. In that case, vb2_start_streaming_called can return true, but when the spinlock is taken and sur40_poll attempts to fetch the next buffer from buf_list, the list is in fact empty. This patch needs to be applied on top of the queued one adding V4L2 support to the sur40 driver.

2015-04-08[media] cx23885: Always initialise dev->slock spinlockDavid Howells
The slock spinlock in the cx23885_dev struct is only initialised if analogue video is being used, but is used in other places too, leading to the attached lockdep complaint. Move the lock initialisation so that it is done unconditionally. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.
