[ Upstream commit ee59be35d7a8be7fcaa2d61fb89734ab5c25e4ee ]
In __pci_register_driver(), the pci core overwrites the dev_groups field of the embedded struct device_driver with the dev_groups from the outer struct pci_driver unconditionally.
Set dev_groups in the pci_driver to make sure it is used.
This was broken since the introduction of pvpanic-pci.
