Subject: [PATCH] drm/msm/dp: Remove encoder pointer from struct msm_dp
Date:   Fri, 24 Jun 2022 17:28:11 -0700
Message-Id: <20220625002811.3225344-1-swboyd@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

We don't need to stash the encoder here. Instead we can simply pass it
around as an argument.
