net: ethernet: mtk_eth_soc: remove cpu_relax in mtk_pending_work
Get rid of cpu_relax in mtk_pending_work routine since MTK_RESETTING is set only in mtk_pending_work() and it runs holding rtnl lock Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
