Subject: drm/ttm:fix wrong decoding of bo_count
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=172423bcc7654a9cc71ff208b8f797e5e11a08af;p=openwrt%2Fstaging%2Fblogic.git

drm/ttm:fix wrong decoding of bo_count

we observe abnormal number from:
/sys/devices/virtual/drm/amdttm/buffer_objects/bo_count

bo_count is atomic_inc which is "int" type,
shouldn't explicitly turn it to unsigned long.
