Subject: [v5 1/3] drm/msm/dpu: clean up references of DPU custom bus scaling
From: Sravanthi Kollukuduru <skolluku@...eaurora.org>
Since the upstream interconnect bus framework has landed
upstream, the existing references of custom bus scaling
needs to be cleaned up.
Changes in v2:
- Fixed build error due to partial clean up
Changes in v3:
- Condense multiple lines into a single line (Sean Paul)
Changes in v4:
- None
Changes in v5:
- None
