Subject: Re: [PATCH v2 26/26] vfio/xe: Add vendor-specific vfio_pci driver
 for Intel graphics

There is absolutely nothing vendor-specific here, it is a device variant
driver.  In fact in Linux basically nothing is ever vendor specific,
because vendor is not a concept that does matter in any practical sense
except for tiny details like the vendor ID as one of the IDs to match
on in device probing.

I have no idea why people keep trying to inject this term again and
again.
