[PATCH v2 14/17] drm/vmwgfx: Refactor surface_define to use vmw_surface_metadata
Roland Scheidegger (VMware)
rscheidegger.oss at gmail.com
Mon Mar 23 23:12:35 UTC 2020
From: Deepak Rawat <drawat.floss at gmail.com>
Makes surface_define cleaner by sending vmw_surface_metadata instead of
all the arguments individually.
v2: fix uninitialized return value, error message
