From 03da0e7ba9e3a1fc700f60913ff6bcb19f7eac2a Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 30 Aug 2013 15:27:16 +0200 Subject: [PATCH] drm/tegra: Parse device tree earlier Parsing the device tree may cause probing to be deferred. Doing this as early as possible prevents any other resources from being requested and enabled, therefore reducing the need to cleanup on deferred probe while at the same time not wasting precious CPU cycles determining if probing needs to be deferred or not.
