72282a88d4 drm: zte: checking for NULL instead of IS_ERR()
drm_dev_alloc() never returns NULL, it only returns error pointers on
error.

0a886f5952 drm: zte: add initial vou drm driver
It adds the initial ZTE VOU display controller DRM driver.  There are
still some features to be added, like overlay plane, scaling, and more
output devices support.  But it's already useful with dual CRTCs and
HDMI monitor working.
