drm/i915/display: Do not re-enable PSR after it was marked as not reliabledrm-intel-next-fixes-2022-03-17
If a error happens and sink_not_reliable is set, PSR should be disabled for good but that is not happening. It would be disabled by the function handling the PSR error but then on the next fastset it would be enabled again in _intel_psr_post_plane_update(). It would only be disabled for good in the next modeset where has_psr will be set false. v2: - release psr lock before continue Fixes: 9ce5884e5139 ("drm/i915/display: Only keep PSR enabled if there is active planes") Reported-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reported-by: Charlton Lin <charlton.lin@intel.com> Cc: Jouni Högander <jouni.hogander@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220311185149.110527-2-jose.souza@intel.com (cherry picked from commit 15f26bdc81f7f03561aaea5a10d87bd6638e1459) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
