From: Glen Lee Date: Mon, 21 Dec 2015 05:18:12 +0000 (+0900) Subject: staging: wilc1000: move all of wilc_wlan_dev_t to struct wilc X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=67e2a07ed800;p=linux-beck.git staging: wilc1000: move all of wilc_wlan_dev_t to struct wilc linux_wlan.c and wilc_wlan.c was separated into two part at the beginning to support various platforms. They are in charge of send/receive control and packet data, so they will be merged into one file wlan.c later. First of all, wilc_wlan_dev_t which is used as global variable of wilc_wlan.c will be moved into struct wilc. This patch moves all members of wilc_wlan_dev_t to struct wilc and use wilc instead of g_wlan. Finally remove wilc_wlan_dev_t and g_wlan.
