Subject: [PATCH 4/9] net: amd-xgbe: disable interrupts during pci removal
Patch-mainline: v5.17-rc4
Git-commit: 68c2d6af1f1e469544d6cbe9a601d96fb9c00e7f
References: git-fixes
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.
