Subject: [PATCH] drm/msm/dpu: Assign missing writeback log_mask
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: a432fc31f03db2546a48bcf5dd69ca28ceb732bf

[ Upstream commit a432fc31f03db2546a48bcf5dd69ca28ceb732bf ]

The WB debug log mask ended up never being assigned, leading to writes
to this block to never be logged even if the mask is enabled in
dpu_hw_util_log_mask via debugfs.

Fixes: 84a33d0fd921 ("drm/msm/dpu: add dpu_hw_wb abstraction for writeback blocks")
