git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

2014-07-17[media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart1-1/+0
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

2014-06-17[media] media: davinci: vpif_capture: drop unneeded module paramsLad, Prabhakar2-64/+1
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.
