From c325f88d7d8a58fbfaaa5bb9c1d39f2cb4fba827 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:32:45 +0200 Subject: drm/nouveau: Don't take dev->struct_mutex in ttm_fini This is only called in driver load/unload paths, no need to grab any locks at all. Also, ttm takes care of itself anyway.
