Hi all,

After commit abe882a39a9c ("drm/amd/display: fix issue with eDP not
detected on driver load") in -next, arm32 allyesconfig builds start
failing at link time:

arm-linux-gnueabi-ld: drivers/gpu/drm/amd/display/dc/core/dc_link.o: in
function `dc_link_detect':
dc_link.c:(.text+0x260c): undefined reference to `__bad_udelay'

arm32 only allows a udelay value of up to 2000, see
arch/arm/include/asm/delay.h for more info.

Please look into this when you have a chance!
Nathan
