From: "Kumar, Mahesh" <mahesh1.kumar@xxxxxxxxx>
Instead of iterating over planes & wm levels in a single function use
skl_compute_wm_level function to interate over WM levels.
Change name of function to skl_compute_wm_levels (Matt).
These changes are to clean-up WM code & will help in making only new
ddb algorithm related changes in later patch in series.
