From 4b24ef1d03cf56008184f458be780da0125fc244 Mon Sep 17 00:00:00 2001 From: Raju Rangoju Date: Wed, 9 Feb 2022 10:02:01 +0530 Subject: [PATCH] net: amd-xgbe: disable interrupts during pci removal [ 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.
