2021-04-02misc/pvpanic: fix return value check in pvpanic_pci_probe()Qiheng Lin
In case of error, the function pci_iomap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

2021-03-28misc/pvpanic: add PCI driverMihai Carabas
Add support for pvpanic PCI device added in qemu [1]. At probe time, obtain the address where to read/write pvpanic events and pass it to the generic handling code. Will follow the same logic as pvpanic MMIO device driver. At remove time, unmap base address and disable PCI device.
