This one is a bit surprising.

Build reference: v5.13.2-267-g7e5885d
Compiler version: x86_64-linux-gcc (GCC) 11.1.0

Building i386:allyesconfig ... failed
--------------
Error log:
drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn20/dcn20_clk_mgr.c: In function 'dcn20_update_clocks_update_dentist':
drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn20/dcn20_clk_mgr.c:154:47: error: 'const struct stream_encoder_funcs' has no member named 'get_fifo_cal_average_level'

Turns out that CONFIG_DRM_AMD_DC_DCN is only enabled with allyesconfig
for ARCH=i386 but not for ARCH=x86_64, and get_fifo_cal_average_level
is indeed not a member of struct stream_encoder_funcs in v5.13.y-queue.
This strongly suggests that commit a39c5ab96adc ("drm/amd/display: Cover
edge-case when changing DISPCLK WDIVIDER") either needs to be dropped
from v5.13.y, or it needs to be backported (and tested) properly.
