[PATCH v4 2/2] drm/msm: remove duplicated code from a6xx_create_address_space
Dmitry Baryshkov

Wed Nov 2 17:54:49 UTC 2022
The function a6xx_create_address_space() is mostly a copy of
adreno_iommu_create_address_space() with added quirk setting. Rework
these two functions to be a thin wrappers around a common helper.
