   4 Subject: [PATCH] media: i2c: ov9281: Change exposure default value
   5  with mode choice
   6
   7 When the exposure range is updated due to changing VBLANK, adopt
   8 the mode default value, not the current default.
   9
  10 Should the specific default value be outside of the min/max range
  11 defined, then the whole update is rejected, which can leave an
  12 invalid exposure range active.
