[PATCH] media: i2c: ov8858: Don't set fwnode in the driver

From: Ondřej Jirman
Date: Sat Oct 07 2023 - 09:00:23 EST


From: Ondrej Jirman <megi@xxxxxx>

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.
