[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Glen Lee <glen.lee@xxxxxxxxx>

commit b22fa80cdbf4ff1056ecddb4efdcc0ede5f5f422 upstream.

This patch fixes build warning and error reported by kbuild test robot.
It is fixed by including netdevice.h.

>> drivers/staging/wilc1000/wilc_wlan_if.h:940:27: warning: 'struct net_device'
 declared inside parameter list
    int wilc_wlan_init(struct net_device *dev, wilc_wlan_inp_t *inp);
>> drivers/staging/wilc1000/wilc_wlan_if.h:940:27: warning: its scope is only
 this definition or declaration, which is probably not what you want
>> drivers/staging/wilc1000/wilc_wlan.c:1954:5: error: conflicting types for
 'wilc_wlan_init'
    int wilc_wlan_init(struct net_device *dev, wilc_wlan_inp_t *inp)
