[PATCH v3 0/2] PCI/ERR: s390/pci: Use pci_uevent_ers() in PCI recovery

[Niklas Schnelle <schnelle@linux.ibm.com>]

Hi Bjorn, Lukas, Mahesh,

This series adds issuing of uevents during PCI recovery on s390. In
developing this I noticed that pci_uevent_ers() ignores
PCI_ERS_RESULT_NEED_RESET. I think this will result in AER not generating a uevent
at the beginning of recovery if drivers request a reset via the voting
on error_detected() returns. This is fixed in the first patch and relied
upon by the s390 recovery code as it also uses the result of
error_detected() though with one device/driver at a time.

Thanks,
Niklas
