Subject: staging: vboxvideo: Drop vbox_bo_unref() helper
X-Git-Tag: v4.20-rc1~72^2~360
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4f6f44086fce7f4d558f762b53c8dcabe5763937;p=thirdparty%2Fkernel%2Flinux.git

staging: vboxvideo: Drop vbox_bo_unref() helper

Drop the unnecessary vbox_bo_unref() helper and directly call ttm_bo_put()
at the single call site.
