From e5ad449be684492f4f58dc169f20926670da7cae Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 1 Jul 2013 22:01:04 +0200 Subject: [PATCH] drm/mm: WARN for unclean mm takedown The usual drm driver has tons of different drm_mm memory managers so the drm error message in dmesg is pretty useless. WARN instead so that we have the full backtrace.
