[PATCH] drm/i915/crt: Downgrade warnings for hotplug failures

From: Chris Wilson
Date: Sun Sep 12 2010 - 15:04:24 EST


These are not fatal errors, so do not alarm the user by filling the
logs with *** ERROR ***. Especially as we know that g4x CRT detection
is a little sticky.

On the one hand the errors are valid since they are warning us of a
stall -- we poll the register whilst holding the mode lock so not even
the mouse will update. On the other hand, those stalls were already present
yet nobody complained.
