   4 Subject: [PATCH] media: i2c: ov9281: Correct min/def vts for 640x400
   5
   6 A VTS of 421 in the 640x400 mode only streams at 130.2fps
   7 instead of the expected ~261fps. This appears to be an invalid
   8 value for the sensor, as a VTS of 422 works fine to give 259.79fps.
   9
  10 Set the minimum (and default) to 422.
