+Subject: [PATCH 0886/2940] drm/amd/display: Copy crc_enabled when duplicating
+ dm_crtc_state
+
+[Why]
+When running igt@kms_plane@pixel-format-pipe-* tests the CRC read will
+time out and the test will fail.
+
+This is because the CRTC is duplicated but the crc_enabled parameter
+isn't copied over to the new dm_crtc_state. CRC reads will time out
+because amdgpu_dm_crtc_handle_crc_irq will no longer call
+drm_crtc_add_crc_entry.
+
+[How]
+Copy crc_enabled when duplicating the state.
