Subject: [PATCH] wifi: rtl8xxxu: Use swap() to improve rtl8xxxu_switch_ports()
Use the swap() macro to simplify the rtl8xxxu_switch_ports() function
and improve its readability. Remove the local variable vif.
Fixes the following Coccinelle/coccicheck warning reported by
swap.cocci:
WARNING opportunity for swap()
Compile-tested only.
