From 28b6a003bcdfa1fc4603b9185b247ecca7af9bef Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Tue, 29 Jun 2021 09:22:14 +0200 Subject: [PATCH] misc/pvpanic-pci: Allow automatic loading The virtual machine monitor (QEMU) exposes the pvpanic-pci device to the guest. On guest side the module exists but currently isn't loaded automatically. So the driver fails to be probed and does not its job of handling guest panic events. Instead of requiring manual modprobe, let's include a device database using the MODULE_DEVICE_TABLE macro and let the module auto-load when the guest gets exposed with such a pvpanic-pci device.
