Subject: media: atomisp: add missing wait_prepare/finish ops Author: Hans Verkuil <hverkuil-ci...@xs4all.nl> Date: Mon Sep 2 10:31:21 2024 +0200 Without these ops the v4l2-compliance blocking wait test will fail. These ops are required to ensure that when VIDIOC_DQBUF has to wait for buffers to arrive, the queue lock is correctly released and retaken. Otherwise the wait for a buffer would block all other queue ioctls.
