## Description

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 stop_streaming when the instance was in IRIS_INST_ERROR, 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 IRIS_INST_ERROR. When userspace attempted    to stop streaming for cleanup, stop_streaming was skipped due to the    added check, preventing proper teardown and leaving the firmware    in an inconsistent state.
