From b8bf6836bf00419e9b714ea70fbd8315b118c3bf Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 9 Jan 2017 19:25:41 +0800 Subject: [PATCH] drm: kirin: use crtc helper drm_crtc_from_index() Use drm_crtc_from_index() to find drm_crtc for given index, so that we do not need to maintain a pointer array in struct kirin_drm_private.
