[igt-dev] [v3 2/2] Move wrapper functions from kms_dsc to kms_dsc_helper
Swati Sharma
swati2.sharma at intel.com
Wed Jan 18 16:50:17 UTC 2023
To add dsc concurrent tests, these wrapper functions can be
reused. Lets create separate helper file to avoid code duplication.
v2: -use of SPDX licence placeholder
-add more parameters to exported functions (Jouni)
v3: -make var static (Jouni)
