Two new warnings are introduced on x86_64 with GCC-8 (defconfig):

-----8<-----
drivers/gpu/drm/drm_edid.o: warning: objtool:
drm_mode_std.isra.34()+0xbc: return with modified stack frame
drivers/gpu/drm/drm_edid.o: warning: objtool:
drm_mode_std.isra.34()+0x0: stack state mismatch: cfa1=3D7+112 cfa2=3D7+8
----->8-----

Bisection points to the quoted commit ("drm/edid: Fix uninitialized
variable in drm_cvt_modes()"), 991fcb77f490 upstream. Reverting makes
the warnings disappear.

Greetings!
