Subject: [PATCH v2 0/2] PCI: NVMe reset quirk

v2: Add bug link, use Samsung vendor ID, add spec references

As discussed in the 2nd patch, at least one NVMe controller sometimes
doesn't like being reset while enabled and another will timeout during
a subsequent re-enable if it happens too quickly after reset.
Introduce a device specific reset quirk for all NVMe class devices so
that we can try to get reliable behavior from them for device
assignment and any other users of the PCI subsystem reset interface.

Patches against current PCI next branch.  Thanks,

Alex
