[igt-dev] [PATCH i-g-t v3 3/3] lib: Use drm_get_param where it is applicable
Lukasz Kalamarz

Mon Nov 26 15:36:24 UTC 2018
With usage of implemented drm_get_param helper function, we can
remove some duplicated code lines across few libs.
v2: Fix typos and missing include
v3: Drop unnecessary getparam structure in one function
