I have no hardware to test it and just to compile it

Thanks for submitting the patch.
The correct way to fix above spare warning is by using cpu_to_le16()
while filing the information in ->beacon_period and ->cap_info because
wilc1000 module expects the data in _le_ byte order.
Please changes the below lines in host_interface.c and resubmit the patch.
param->beacon_period = bss->beacon_interval;
param->cap_info = bss->capability;
to
param->beacon_period = cpu_to_le16(bss->beacon_interval);
param->cap_info = cpu_to_le16(bss->capability);
