From db4448f78d5982997751120ca358c97a7f96e122 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:32:49 +0200 Subject: [PATCH] drm/amdgpu: Don't take dev->struct_mutex in bo_force_delete MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It really doesn't protect anything which doesn't have other locks already. Also this is run from driver unload code so not much need for locks anyway. Same changes as for radeon really.
