From 01934c2a691882185b3021d437df13bcba07711d Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 19 Dec 2014 11:21:32 +0100 Subject: drm/fb-helper: Propagate errors from initial config failure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.
