[PATCH 5.2 086/144] drm/msm/dpu: Correct dpu encoder spinlock initialization

From: Greg Kroah-Hartman
Date: Wed Aug 14 2019 - 13:06:01 EST


[ Upstream commit 2e7b801eadbf327bf61041c943e5c44a5de4b0e5 ]

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