Subject: [PATCH 4.19 33/49] net: amd-xgbe: disable interrupts during pci removal
From: Raju Rangoju <Raju.Rangoju@....com>
[ 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")
