[PATCH 05/11] drm/vmwgfx: Use preprocessor macro for cmd struct

Deepak Singh Rawat drawat at vmware.com
Fri Apr 5 18:40:38 UTC 2019


Use preprocessor macro for repetitive device command struct format.

v2: Name-space distinction for preprocessor macro.

v3: Struct name as macro parameter and rebase.
