2014-06-17[media] media: davinci: vpif_capture: fix v4l-compliance issuesLad, Prabhakar
This patch does the following: 1: sets initial default format during probe. 2: removes spurious messages. 3: optimize vpif_s/try_fmt_vid_out code.

2014-06-17[media] media: davinci: vpif_capture: drop unneeded module paramsLad, Prabhakar
Remove bogus 'numbuffers' and 'bufsize' module options. The number of buffers and buffer sizes are determined by VIDIOC_REQBUFS and VIDIOC_S_FMT and the amount of available memory (in the case of the MMAP stream I/O mode) and not by module options. These module params are a left-over from the original montavista code that used these parameters to pre-allocate the memory needed for the buffers. The code that allocated those buffers was never upstreamed since by the time the drivers were added to the kernel the TI cmem module could be used in combination with the USERPTR mode to reserve and pass physically contiguous memory pointers around. These days of course CMA is used instead of cmem. This patch removes these module options altogether since they no longer do what they originally were designed for. They should never have been part of the upstreamed code in the first place, so they've been pointless ever since 2.6.32 when this driver first appeared in the mainline kernel.
