From cd5428a5447cc6ca77ec6547d6f86834b205eac7 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 21 Jan 2013 23:42:49 +0100 Subject: [PATCH] drm/: simplify ->fb_probe callback The fb helper lost its support for reallocating an fb completely, so no need to return special success values any more.
