Subject: [PATCH v17 03/20] drm/msm/gpu: Add dev_to_gpu() helper
Date: Sat,  5 Sep 2020 13:04:09 -0700	[thread overview]
Message-ID: <20200905200454.240929-4-robdclark@gmail.com> (raw)
In-Reply-To: <20200905200454.240929-1-robdclark@gmail.com>

From: Rob Clark <robdclark@chromium.org>

In a later patch, the drvdata will not directly be 'struct msm_gpu *',
so add a helper to reduce the churn.
