[igt-dev] [PATCH i-g-t v4 2/4] Moved common function in kms_color and kms_color_chamelium to kms_color_helper.c
Kunal Joshi
kunal1.joshi at intel.com
Thu Jan 23 08:00:40 UTC 2020
kms_color and kms_color_chamelium shared common functions.
Moved them to tests/kms_color_helper.c to avoid code duplication.
(v4)
Made a library kms_color_helper.c which is specific to
kms_color and kms_color_chamelium.
