drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_hubbub.c: In function hubbub31_verify_allow_pstate_change_high':
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_hubbub.c:994:17: error: implicit declaration of function 'udelay' [-Werror=implicit-function-declaration]

Caused by "drm-amd-display-add-pstate-verification-and-recovery-for-dcn31.patch".
Explicitly includng <linux/delay.h> in dcn31_hubbub.c fixes it.

Current mainline version of dcn31_hubbub.c does not explicitly include
<linux/delay.h>, so there seems to be some general inconsistency wrt.
which dcn module includes what.
