Subject: [PATCH] drm/i915: shut up spurious WARN in the gtt fault handler
Date: Wed, 17 Oct 2012 11:17:16 +0200	[thread overview]
Message-ID: <1350465436-15328-1-git-send-email-daniel.vetter@ffwll.ch> (raw)

-ENOSPC can happen if userspace is being simplistic and tries to map a
too big object. To aid further spurious WARN debugging, also print out
the error code.
