Hello,
We're observing the following build failure with v4.12-rc3, latest linux.git and linux-next.git:

My guess is the symbols used by the exynos drm module are not exported:
cec_notifier_set_phys_addr_from_edid cec_notifier_set_phys_addr cec_notifier_put cec_notifier_get
Can you please look into fixing this?
Thanks for reporting.
Will check and fix it.
Thanks, Inki Dae
