Subject: [PATCH 0737/1085] media/i2c: ov7251: Switch from V4L2_CID_GAIN to
|
||
|
V4L2_CID_ANALOGUE_GAIN
|
||
|
|
||
|
The mainline driver has implemented analogue gain using the control
|
||
|
V4L2_CID_GAIN instead of V4L2_CID_ANALOGUE_GAIN.
|
||
|
|
||
|
libcamera requires V4L2_CID_ANALOGUE_GAIN, and therefore fails.
|
||
|
|
||
|
Update the driver to use V4L2_CID_ANALOGUE_GAIN.
|
||
