  n MHI driver, there are some companies' product still do not have their
own PCI vendor macro. So we add it here to make the code neat. Ref ID
could be found in link https://pcisig.com/membership/member-companies.

v3: Separate different vendors into different patch.

v2: Update vendor ID to the right location sorted by numeric value.

Why did you ignore the comment at the top of this file saying that new
entries are not needed to be added, especially for just one user?

Hi Greg,
 Actually I didn't see this notice before committing this patch. 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.

Thanks
Slark Xiao

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

Hi Greg,
Thanks for your explanation. 

Hi Mani,
  Is there a need to update these vendor ids as macro in
pci_generic.c?

Thanks.

It is not really needed but for convenience you could add a macro in
pci_generic.c itself.
