Linkai Gong 92a9eebd2a drm/amd/display: fix dc_lock leak on GPU reset error paths ... On GPU reset, dm_suspend() takes dc_lock and leaves it for dm_resume() to drop. If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails, the function returns with the lock still held. The matching resume path is then skipped, so every later dc_lock take hangs. Release the cached DC state and unlock before returning the error. Fixes: 3cf7a0bc87 ("drm/amd/display: Catch failures for amdgpu_dm_commit_zero_streams()") Fixes: 2b6943df54 ("drm/amd/display: Pass up errors for reset GPU that fails to init HW") Cc: stable@vger.kernel.org Signed-off-by: Linkai Gong <gonglinkai@kylinos.cn> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>		2026-08-25 18:24:30 -04:00
