From ac620ba3d09bc96eca203658ad2e145adf911ac3 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 29 Dec 2016 20:41:29 +0800 Subject: [PATCH] drm: zte: use crtc helper drm_crtc_from_index() Function zx_find_crtc() does the exactly same thing as what crtc helper drm_crtc_from_index() provides. Use the helper to save some code.
