Subject: drm/i915/gvt: Enable gtt initialization for BXT.
X-Git-Tag: v4.19-rc1~138^2~35^2~5^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=665004b8f50612d1e354eb9abd6d97e6eb85a619;p=thirdparty%2Fkernel%2Flinux.git

drm/i915/gvt: Enable gtt initialization for BXT.

Initialize BXT gtt as SKL/KBL.

v2: All supported platforms share the same gtt ops.
    Remove the platform check by now and let is_supported_device()
    be the gate keeper.
