Subject: switchdev: fix return value of switchdev_port_fdb_dump in case of error
X-Git-Tag: v4.3-rc1~28^2~45
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0890cf6cb6ab1af650025670b1a839671a9a3fcb;p=profile%2Fcommon%2Fplatform%2Fkernel%2Flinux-artik7.git

switchdev: fix return value of switchdev_port_fdb_dump in case of error

switchdev_port_fdb_dump is used as .ndo_fdb_dump. Its return value is
idx, so we cannot return errval.

Fixes: 45d4122ca7cd ("switchdev: add support for fdb add/del/dump via switchdev_port_obj ops.")
