From 0f26e5ce3e62c66ec0717b22d82eee8e29fe7b4e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noralf=20Tr=C3=B8nnes?= Date: Sat, 8 Sep 2018 15:46:41 +0200 Subject: drm/sti: Use drm_fbdev_generic_setup() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). If drm_fbdev_generic_setup() fails, an error is printed by the function. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.
