Subject: net: bfin_mac: Use platform_register/unregister_drivers()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=36b9ddd53587537ee9584f43a2713474000346cd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net: bfin_mac: Use platform_register/unregister_drivers()

These new helpers simplify implementing multi-driver modules and
properly handle failure to register one driver by unregistering all
previously registered drivers.
