Commit Message

Laurent Pinchart March 23, 2020, 10:19 a.m. UTC 
Replace initialization of static const v4l2_fmtdesc instances that
specify every struct member with designated initializers. This allows
not zeroing the reserved fields explicitly, and will avoid a need to
patch these drivers every time a reserved field is repurposed.
