From 2a8c6edfd2a888085ae0ddaf6c3ea3f529fdc4e8 Mon Sep 17 00:00:00 2001 From: Liu Ying Date: Thu, 19 Jun 2014 16:01:44 +0800 Subject: [PATCH] drm/fb-helper: Remove unnecessary list empty check in drm_fb_helper_debug_enter() The following list empty check is unnecessary because we would still do nothing real and return 'val' if my_list is empty. if (list_empty(&my_list)) return val; list_for_each_entry(pos, &my_list, member) { ... } return val; This patch removes the unnecessary check in drm_fb_helper_debug_enter().
