Subject: staging: wilc1000: remove io_type of wilc_wlan_dev_t
X-Git-Tag: v4.5-rc1~122^2~199
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3629a9ee36a6f8fcbc764e811a2fe0e492f739f;p=platform%2Fkernel%2Flinux-exynos.git

staging: wilc1000: remove io_type of wilc_wlan_dev_t

io_type of wilc_wlan_dev_t is unneeded, we can use io_type of struct wilc.
Remove io_type of wilc_wlan_dev_t and use io_type of wilc.
