From d3e376f52d095103ca51dbda4d6ff8aaf488f98f Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Nov 2015 10:32:49 +0100 Subject: [PATCH] drm/gma500: Use correct unref in the gem bo create function This is called without dev->struct_mutex held, we need to use the _unlocked variant. Never caught in the wild since you'd need an evil userspace which races a gem_close ioctl call with the in-progress open.
