Subject: [PATCH v2] media: i2c: ov08x40: Make remove callback return void

In commit ed5c2f5fd10d ("i2c: Make remove callback return void") drivers
were updated to remove the return value of the remove callback, and
return void.

The OV08x40 was added after this commit but was not compile tested at
the time due to a KConfig issue, and this warning was missed.

Reported-by: kernel test robot <lkp@...el.com>
Fixes: 38fc5136ac16 ("media: i2c: Add ov08x40 image sensor driver")
Signed-off-by: Kieran Bingham <kieran.bingham+renesas@...asonboard.com>
---

How come it's always after sending that it is easier to notice the
small mistakes like ordering of the commits to blame.

v2:
 - Fix wording of commit message to show that the driver patch came
   after the change in remove call back API.
