From 0a5b7b0bd97a212f5d8d28c5011b04a45dfb006e Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 3 Sep 2013 19:00:09 -0400 Subject: drm/radeon: add spinlocks for indirect register accesss This adds spinlocks to protect access to other indirect register apertures. These indirect spaces are used pretty infrequently and we haven't had an reported problems, but better safe than sorry.
