X-Git-Tag: v4.9.8~2476^2~552
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3b5dde70b18e2aa05138466cd6b83f6529d4df0d;p=platform%2Fkernel%2Flinux-rpi3.git

net: mv643xx: 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.
