From 764ba3ae511adddfa750db290ac8375d660ca5b9 Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Mon, 29 Jun 2015 16:12:13 +0300 Subject: [PATCH] block: remove redundant check before g_slist_find() An empty GSList is represented by a NULL pointer, therefore it's a perfectly valid argument for g_slist_find() and there's no need to make any additional check.
