media: i2c: Switch exposure control unit to lines
The ov8865 driver currently has the unit of the V4L2_CID_EXPOSURE control as 1/16th of a line. This is what the sensor expects, but isn't very intuitive. Switch the control to be in units of a line and simply do the 16x multiplication before passing the value to the sensor. The datasheet for this sensor gives minimum exposure as 2 lines, so take the opportunity to correct the lower bounds of the control. Signed-off-by:Daniel Scally <djrscally@gmail.com> Signed-off-by:
