File 0502-drm-sun4i-Fix-a-return-value-in-case-of-error.patch of Package drm.7971
From ef5760f9600019dd13302263c1532706fe469c05 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Date: Fri, 18 Nov 2016 19:18:47 +0100 Subject: [PATCH] drm/sun4i: Fix a return value in case of error [ Upstream commit 0f0861e31e3c59ca4bc1ec59d99260cfca79740e ] If 'sun4i_backend_drm_format_to_layer()' does not return 0, then 'val' is left unmodified. As it is not initialized either, the return value can be anything. It is likely that returning the error code was expected here. As the only caller of 'sun4i_backend_update_layer_formats()' does not check the return value, this fix is purely theorical.
