Subject: [PATCH] media: i2c: ov7251: Add V4L2_CID_HBLANK control
|
|
|
|
HBLANK is a fixed value in this driver, so add as a fixed
|
|
read-only control.
|
|
The value is updated during set_format as the V4L2 control is
|
|
dependent on width, even though only one width is actually
|
|
defined.
|
|
