[PATCH 1/2] drm/etnaviv: fail probe if core or bus clock are absent

[Lucas Stach]

The devicetree documentation states that those are required properties,
so the driver should refuse to probe if those are absent to be
consistent. This will also allow to drop some error checking from the
clock enable/disable paths.
