From 35a4569e72eec439a2d7e6c860ed42c518aa8f76 Mon Sep 17 00:00:00 2001 From: Glen Lee Date: Mon, 21 Dec 2015 14:18:29 +0900 Subject: [PATCH] staging: wilc1000: linux_wlan_sdio.c: move all the codes to wilc_sdio.c To Combine linux_wlan_sdio.c and wilc_sdio.c as one file, move all the codes in linux_wlan_sdio.c to wilc_sdio.c, and make functions static only. No Modification has not been made except static, just moved them. Function declaration in linux_wlan_sdio.h is needless, so just remove them. linux_wlan_sdio.[ch] will be deleted in the next patch.
