From: Arnd Bergmann Date: Mon, 16 Nov 2015 14:04:59 +0000 (+0100) Subject: staging/wilc1000: move wilc_wlan_inp_t into struct wilc X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4bd7baf04de9ce5f8117da30d5ee2368f3c41b3e;p=linux-beck.git staging/wilc1000: move wilc_wlan_inp_t into struct wilc wilc_wlan_inp_t is an unnecessary indirection and requires linux_wlan.c to have knowledge of the specific sdio and spi front-ends. This removes the structure and places io_type directly inside the struct wilc.
