Run 'modinfo <name-of-driver>'. For pci drivers, each "alias" line will show some kind of pci information that the driver binds to. For example: # modinfo nvme filename: /lib/modules/5.12.0+/kernel/drivers/nvme/host/nvme.ko <...> alias: pci:v*d*sv*sd*bc01sc08i02* alias: pci:v0000106Bd00002005sv*sd*bc*sc*i* alias: pci:v0000106Bd00002003sv*sd*bc*sc*i* alias: pci:v0000106Bd00002001sv*sd*bc*sc*i* alias: pci:v00001D0Fd0000CD02sv*sd*bc*sc*i* <...> The first "alias" binds to any vendor device that has a matching class code. The remaining lines show a specific vendor:device identifier.
