From 75bcb0545b56eab2d69dbccf95ff7505b7114e5d Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 9 Jan 2017 19:25:44 +0800 Subject: [PATCH] drm: tegra: use crtc helper drm_crtc_from_index() Function tegra_crtc_from_pipe() does the exactly same thing as what crtc helper drm_crtc_from_index() provides. Use the helper to save some code.
