I even discussed it with the maintainer for several times and nobody show me this rule. I have a concern, some IOT module vendors, like QUECTEL, CINTERION(THALES), SIERRA,ROLLING and so on, they only produce IOT modules without other hardware with PCIe interface, and they applied for their own VID. But they can't get a their own VENDOR MARCO? This seems unreasonable. This change should be harmless and make the code neat. This is my opinion.

It causes a _LOT_ of churn and merge issues when everyone is adding new entries to a single file. Which is why, 15+ years ago, we made the decision that if a vendor or device id is only needed in one file, then it should not be added to the pci_ids.h file. No need to change that now, please just put the vendor id in the single driver that it is needed in. thanks, greg k-h ^ permalink raw reply [flat|nested] 7+ messages in thread
