Subject: drm/ttm: initialize the system domain with defaults v2
X-Git-Tag: v5.10-rc1~123^2~26^2~202
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=418d2ad1ac521acc46f74f6bcbc8c1158d077346;p=thirdparty%2Fkernel%2Flinux.git

drm/ttm: initialize the system domain with defaults v2

Instead of repeating that in each driver.

v2: keep the caching limitation for VMWGFX for now.
