From 187d5edf1eaa8f6dc29f8a39fc10225d74a80d16 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Thu, 3 Jul 2014 15:10:31 +0200 Subject: [PATCH] drm/exynos/ipp: remove incorrect checks of list_first_entry result list_first_entry does not return NULL on empty list so this check does not make sense. Moreover there is already code which prevents calling list_first_entry on empty lists.
