Hi, according to https://github.com/torvalds/linux/blob/master/Documentation/PCI/pci-error-recovery.txt as part of AER handling, struct pci_error_handlers{} is implemented by endpoint drivers to handle device specific recovery steps for "struct pci_driver". But we have a platform_driver which implements "struct pci_host_bridge" which also supports AER capability how can we support pci_error_handlers() for the host bridge drivers ? Thanks, Subrahmanya.
