From 1029117127540fef4edcf4f0887dc3e1f7d5adb2 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Fri, 9 Feb 2018 17:22:47 +0100 Subject: [PATCH] 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 Signed-off-by: David S.
