Subject: [PATCH net-next 3/6] mlxsw: spectrum_router: Publish mlxsw_sp_rif_find_by_dev()

From: Petr Machata <petrm@...lanox.com>

In order to guard against removal of a PVID for which a FID was
allocated, spectrum_switchdev needs to first determine whether there is
a RIF associated with a given bridge. To that end, publish a preexisting
function mlxsw_sp_rif_find_by_dev().
