From 442cbc86b9b75ea36d5abc97e25ae349476f9590 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 15 Dec 2020 12:46:36 +0200 Subject: drm/omap: dsi: drop useless channel checks A DSI peripheral can have virtual channel ID of 0-3. This should be always the case, and there's no need in the driver to validate the channel.
