AI-suggested
The issue has been resolved by reverting the problematic commit in Linux kernel version 6.18.3. Users should update to this or later versions where the fix is applied to ensure proper stop_streaming behavior and avoid the described regressions.
Description
A vulnerability in the Linux kernel related to the media subsystem's iris driver was addressed by reverting a previous commit that added a sanity check for stop streaming. The reverted check caused multiple regressions by skipping stop_streaming when the instance was in an error state, leading to buffers not being returned properly and improper teardown of firmware in error scenarios.
