[PATCH 1/2] drm/msm/dpu: Drop enable and frame_count parameters from dpu_hw_setup_misr()

From: Jessica Zhang
Date: Thu Nov 30 2023 - 20:31:16 EST


Drop the enable and frame_count parameters from dpu_hw_setup_misr() as they
are always set to the same values.

In addition, replace MISR_FRAME_COUNT_MASK with MISR_FRAME_COUNT as
frame_count is always set to the same value.

Fixes: 7b37523fb1d1 ("drm/msm/dpu: Move MISR methods to dpu_hw_util")
