From b03314e22571783488828f7f38fa708cbd3a1888 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 16 Nov 2015 15:05:01 +0100 Subject: [PATCH] staging/wilc1000: unify device pointer struct wilc has two pointers to store the device, one for sdio_func and one for spi_device. By changing the pointer to a 'struct device', we can simplify the logic and avoid a few #ifdefs.
