[Intel-gfx] [PATCH i-g-t] lib: Rename tiling variables to modifier if that's what they contain

Tomeu Vizoso tomeu.vizoso at collabora.com
Thu Nov 10 10:25:49 UTC 2016


Though right now modifiers are only used to specify tiling, there are
different constants for them and naming them differently should help
with not mixing them.
