Please strive for improved code for human readers and
not just shutting up checkpatch.

Depending on alignment, perhaps a good bit of this code
could use ether_addr_<foo> functions.

				wilc_set_wfi_drv_handler(vif, wilc_get_vif_idx(vif),
							 ether_addr_equals(wl->vif[i ^ 1]->bssid,
									   wl->vif[i ^ 1]->src_addr));

The code could also be restructured to reduce
indentation by using if / continue;

		if (ndev != wl->vif[i]->ndev)
			continue;

Using a temporary for the repeated use of
wilc_get_vif_idx(vif) would also help code length.

		ether_addr_copy()

etc.
