[10/14] drm/msm/dpu: Remove encoder->enable() hack

Commit Message

Sean Paul Sept. 13, 2021, 5:57 p.m. UTC

From: Sean Paul <[e-mail]>

encoder->commit() was being misused because there were some global
resources which needed to be tweaked in encoder->enable() which were not
accessible in dpu_encoder.c. That is no longer true and the redirect
serves no purpose any longer. So remove the indirection.
