Subject: [PATCH v2 3/3] drm/msm/dpu: drop VBIF indices
Date: Tue, 19 Apr 2022 19:20:30 +0300	[thread overview]
Message-ID: <20220419162030.1287562-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220419162030.1287562-1-dmitry.baryshkov@linaro.org>

We do not expect to have other VBIFs. Drop VBIF_n indices and always use
VBIF_RT and VBIF_NRT.
