If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails,\nthe function returns with the lock still held. The matching resume path\nis then skipped, so every later dc_lock take hangs.\n\nRelease the cached DC state and unlock before returning the error.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/295d2bf42061db490254e748f9344545bb7faf19","tags":[]},{"url":"https://git.kernel.org/stable/c/92a9eebd2a1f892fe482154d83f9f1626bc73d3b","tags":[]},{"url":"https://git.kernel.org/stable/c/dac29cbb405b912742f4f7eda833cec8e7a53780","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
