Subject: media: ov9640: Don't set format in sub-device state
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Wed Dec 6 19:25:07 2023 +0200
For the purpose of setting old non-pad based sub-device try format as a
basis for VIDIOC_TRY_FMT implementation, there is no need to set the
format in the sub-device state. Drop the assignment to the state, which
would result in a NULL pointer dereference.
Fixes: fd17e3a9a788 ("media: i2c: Use accessors for pad config 'try_*' fields")
