The full series is available at https://lore.kernel.org/linux-pci/20210729203740.1377045-1-u.kleine-koenig@xxxxxxxxxxxxxx/ 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@xxxxxxxxxxxxxx ).
