net: stmmac: remove redundant enable of PMT irq
For dwmac4, GMAC_INT_DEFAULT_ENABLE already includes GMAC_INT_PMT_EN, so it is redundant to check if hw->pmt is set, and if so, setting the bit again. For dwmac1000, GMAC_INT_DEFAULT_MASK does not include GMAC_INT_DISABLE_PMT, so it is redundant to check if hw->pmt is set, and if so, clearing an already cleared bit. Improve code readability by removing this redundant code. Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Signed-off-by: David S. Miller <davem@davemloft.net>
