Hi,
Currently, in the event of AER/DPC, PCI core will try to reset the slot and its
subordinate devices by invoking bridge control reset and FLR. But in some
cases like AER Fatal error, it might be necessary to reset the slots using the
PCI host bridge drivers in a platform specific way (as indica

From: Manivannan Sadhasivam
A PCI device is just another peripheral in a system. So failure to
recover it, must not result in a kernel panic. So remove the TODO which
is quite misleading.
