The full series is available at

	https://lore.kernel.org/linux-pci/20210729203740.1377045-1-u.kleine-koenig@pengutronix.de/

All patches but #4 only touch drivers/pci/ (and include/linux/pci.h) and
it seemed excessive to me to send all patches to all people. It seems at
least for you I balanced this wrongly. The short version is that patch
#3 introduces

	+#define pci_driver_of_dev(pdev) ((pdev)->driver)

which allows to do the stuff done in patch #4 and then patch #5 does

	-#define pci_driver_of_dev(pdev) ((pdev)->driver)
	+#define pci_driver_of_dev(pdev) ((pdev)->dev.driver ? to_pci_driver((pdev)->dev.driver) : NULL)

plus some cleanups.

If you want I can send you a bounce (or you try

	b4 am 20210729203740.1377045-1-u.kleine-koenig at pengutronix.de

).

Best regards and thanks for caring,
Uwe
