[PATCH v5 4/6] drm/msm/dpu: stop embedding dpu_hw_blk into dpu_hw_intf

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now as dpu_hw_intf is not hanled by dpu_rm_get_assigned_resources, there
is no point in embedding the (empty) struct dpu_hw_blk into dpu_hw_intf
(and using typecasts between dpu_hw_blk and dpu_hw_intf). Drop it and
use dpu_hw_intf directly.
