* [media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart2014-07-171-3/+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.

* [media] media: remove the setting of the flag V4L2_FL_USE_FH_PRIORamakrishnan Muthukrishnan2014-07-041-1/+0
| | | | | | | | | | | Since all the drivers that use `struct v4l2_fh' use the core priority checking, the setting of the flag in the drivers can be removed.
