Subject: [PATCH] media: i2c: ov5647: Neither analogue gain nor
|
||
|
|
exposure need EXECUTE_ON_WRITE
|
||
|
|
|
||
|
|
The controls for analogue gain and exposure were defined with
|
||
|
|
V4L2_CTRL_FLAG_EXECUTE_ON_WRITE. This is not required as we only need
|
||
|
|
to send changes to the sensor.
