From bdecd83546352e0cdf54f64d8d6206f1fef32d75 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noralf=20Tr=C3=B8nnes?= Date: Wed, 15 Nov 2017 15:19:58 +0100 Subject: [PATCH] drm/arm/mali: Use drm_fb_cma_fbdev_init/fini() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.
