Subject: [PATCH AUTOSEL 6.5 28/31] media: i2c: ov8858: Don't set fwnode in the driver
From: Ondrej Jirman <megi@....cz>
[ Upstream commit c46f16f156ac58afcf4addc850bb5dfbca77b9fc ]
This makes the driver work with the new check in
v4l2_async_register_subdev() that was introduced recently in 6.6-rc1.
Without this change, probe fails with:
ov8858 1-0036: Detected OV8858 sensor, revision 0xb2
ov8858 1-0036: sub-device fwnode is an endpoint!
ov8858 1-0036: v4l2 async register subdev failed
ov8858: probe of 1-0036 failed with error -22
This also simplifies the driver a bit.
