Subject: [PATCH] drm/mm: Don't WARN if drm_mm_reserve_node
Date: Mon,  7 Apr 2014 23:25:20 +0200	[thread overview]
Message-ID: <1396905920-30049-1-git-send-email-daniel.vetter@ffwll.ch> (raw)

Jesse's BIOS fb reconstruction code actually relies on the -ENOSPC
return value to detect overlapping framebuffers (which the bios uses
always when lighting up more than one screen). All this fanciness
happens in intel_alloc_plane_obj in intel_display.c.

Since no one else uses this we can savely remove the WARN without
repercursions.
