From 99e67a615aa02ba6073f88e667099e6a2f5172f5 Mon Sep 17 00:00:00 2001

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.
