Subject: [PATCH] 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.
