From 53dc0cfea3cfec470418730df7abfef401f75a4d Mon Sep 17 00:00:00 2001 From: Glen Lee Date: Tue, 20 Oct 2015 17:13:57 +0900 Subject: [PATCH] staging: wilc1000: wilc1000_wlan_deinit: change argument and use wilc This patch changes function argument wilc with net_device and use nic->wilc instead of global variable g_linux_wlan. The null check codes should be placed before it is used so move it.
