[PATCH v7 08/20] drm: Probe panels on demand

From: Tomeu Vizoso
Date: Tue Sep 29 2015 - 05:15:00 EST

When looking up a panel through its OF node, probe it if it hasn't

The goal is to reduce deferred probes to a minimum, as it makes it very
cumbersome to find out why a device failed to probe, and can introduce
very big delays in when a critical device is probed.
