[PATCH net-next 4/6] devlink: Clean registration of devlink port
From: Leon Romanovsky
Date: Wed Nov 17 2021 - 13:27:04 EST
From: Leon Romanovsky <leonro@xxxxxxxxxx>
devlink_port_register() is in-kernel API and as such can't really fail
as long as driver author didn't make a mistake by providing already existing
port index. Instead of relying on various error prints from the driver,
convert the existence check to be WARN_ON(), so such a mistake will be
caught easier.
As an outcome of this conversion, it was made clear that this function
should be void and devlink->lock was intended to protect addition to
port_list.
Signed-off-by: Leon Romanovsky <leonro@xxxxxxxxxx>
