I am getting a kernel build error at version 5.6-rc1:
drivers/gpu/drm/drm_edid.c: In function 'cea_mode_alternate_timings': drivers/gpu/drm/drm_edid.c:3275:2: error: call to '__compiletime_assert_3282' declared with attribute error: BUILD_BUG_ON failed: cea_mode_for_vic(8)->vtotal != 262 || cea_mode_for_vic(9)->vtotal != 262 || cea_mode_for_vic(12)->vtotal != 262 || cea_mode_for_vic(13)->vtotal != 262 || cea_mode_for_vic(23)->vtotal != 312 || cea_mode_for_vic(24)->vtotal != 312 || cea_mode_for_vic(27)->vtotal != 312 || cea_mode_for_vic(28)->vtotal != 312 make[4]: *** [drivers/gpu/drm/drm_edid.o] Error 1
Kernel configuration: make qcom_defconfig
(arch/arm/configs/qcom_defconfig)
Compiler is arm-eabi-gcc 4.6.x
The build error goes away if I revert:
f7655d42fcee drm/edid: Add CTA-861-G modes with VIC >= 193
The build error also goes away if I comment out the two lines added to cea_mode_for_vic():
if (vic >= 193 && vic < 193 + ARRAY_SIZE(edid_cea_modes_193)) return &edid_cea_modes_193[vic - 193];
