CVE-2026-43151: Revert "media: iris: Add sanity check for stop streaming"
In the Linux kernel, the following vulnerability has been resolved:
Revert "media: iris: Add sanity check for stop streaming"
This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4.
Revert the check that skipped stopstreaming when the instance was in IRISINSTERROR, as it caused multiple regressions:
1. Buffers were not returned to vb2 when the instance was already in error state, triggering warnings in the vb2 core because buffer completion was skipped.
2. If a session failed early (e.g. unsupported configuration), the instance transitioned to IRISINSTERROR. When userspace attempted to stop streaming for cleanup, stopstreaming was skipped due to the added check, preventing proper teardown and leaving the firmware in an inconsistent state.
