[PATCH 07/14] powernv/eeh: Use generic code to handle hot resets

2019-09-03 Thread Oliver O'Halloran
When we reset PCI devices managed by a hotplug driver the reset may generate spurious hotplug events that cause the PCI device we're resetting to be torn down accidently. This is a problem for EEH (when the driver is EEH aware) since we want to leave the OS PCI device state intact so that the devic
