Subject: [PATCH 0/2] gpu/drm: ingenic: Handle disabled drivers

Hi,

A small patchset to make sure that the ingenic-drm driver won't fail to
probe if an optional device (e.g. HDMI chip) has its driver disabled in
the kernel config.

Since most of the boards using the ingenic-drm driver have a LCD panel
attached, the drivers for external devices (be it a HDMI transmitter or
a TV encoder) really are optional and shouldn't prevent the DRM driver
from probing.

Cheers,
-Paul
