Subject[PATCH AUTOSEL 5.2 41/76] drm/msm/dpu: Correct dpu encoder spinlock initialization
Date
From: Shubhashree Dhar <dhar@codeaurora.org>

[ Upstream commit 2e7b801eadbf327bf61041c943e5c44a5de4b0e5 ]

dpu encoder spinlock should be initialized during dpu encoder
init instead of dpu encoder setup which is part of modeset init.
