[PATCH 5.4 49/71] net: amd-xgbe: disable interrupts during pci removal

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Raju Rangoju <Raju.Rangoju@xxxxxxx>

[ Upstream commit 68c2d6af1f1e469544d6cbe9a601d96fb9c00e7f ]

Hardware interrupts are enabled during the pci probe, however,
they are not disabled during pci removal.

Disable all hardware interrupts during pci removal to avoid any
issues.

Fixes: e75377404726 ("amd-xgbe: Update PCI support to use new IRQ functions")
