   4 Subject: [PATCH 21/43] v4l: Replace enums with fixed-sized fields in public structure
   5
   6 The v4l2_mbus_framefmt structure will be part of the public userspace
   7 API and used (albeit indirectly) as an ioctl argument. As such, its size
   8 must be fixed across userspace ABIs.
   9
  10 Replace the v4l2_field and v4l2_colorspace enums by __u32 fields and add
  11 padding for future enhancements.
