[PATCH v3 2/9] drm: hold master_lookup_lock when releasing a drm_file's master

When drm_file.master changes value, the corresponding drm_device.master_lookup_lock should be held. In drm_master_release, a call to drm_master_put sets the file_priv->master to NULL, so we protect this section with drm_device.master_lookup_lock. Signed-off-by: Desmond Cheong Zhi Xi --- drivers
