Subject: [PATCH v2 3/4] drm/msm: get rid of msm_iomap_size
Date: Tue, 27 Apr 2021 03:18:27 +0300	[thread overview]
Message-ID: <20210427001828.2375555-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210427001828.2375555-1-dmitry.baryshkov@linaro.org>

Instead of looping throught the resources each time to get the DSI CTRL
area size, get it at the ioremap time.
