Which default config are you talking about? This compiles fine with all drm-misc defconfig, x86 defconfig and allmodconfig.
The drm_hdmi_avi_infoframe_colorimetry() function is belong to the drm_display_helper.ko kernel module, it get called from hdmi_generate_avi_infoframe() in drm_atomic_state_helper.c. While drm_atomic_state_helper.c belongs to drm_kms_helper.ko. Therefore drm_kms_helper.ko is dependent on drm_display_helper.ko implicitly. So we probably should select it. -- Best regards, Sui
