From 44a11920ac39fe7fe5191d72c0822ff2a4c3b83d Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 13 Aug 2022 10:30:34 +0200 Subject: [PATCH] media: atomisp-ov2680: Don't take the input_lock for try_fmt calls. On ov2680_set_fmt() calls with format->which == V4L2_SUBDEV_FORMAT_TRY, ov2680_set_fmt() does not talk to the sensor, so there is no need to lock the dev->input_lock mutex in this case.
