From: Chris Wilson Date: Thu, 5 Jul 2018 06:56:51 +0000 (+0100) Subject: drm/i915: Remove defunct i915->vm_list X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cef08fdc743c4211aeba69dd23408093d59da241;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Remove defunct i915->vm_list No longer used and can be removed. One less global that currently demands struct_mutex protection.
