[igt-dev] [PATCH i-g-t v4 4/4] lib: Adjust refactored gpu_fill library to our coding style

Katarzyna Dec katarzyna.dec at intel.com
Tue Apr 10 08:12:32 UTC 2018


While I am making changes in gpgpu and media fill area let's
adjust code to our coding style.

v2: rebased on series new version (patch is now last from
series so change seems larger)
v3: rebased
