Please post this in the series where you add the future drivers.

We don't add new things to pci_ids.h unless they are actually used by
more than one driver because it complicates life for people who
backport things (there's a note at the top of the file about this).

https://pcisig.com/membership/member-companies?combine=8848 says this
Vendor ID belongs to:

  Wuxi Micro Innovation Integrated Circuit Design Co.,Ltd

I suppose "MUCSE" connects with that somehow.

It's nice if people can connect PCI_VENDOR_ID_MUCSE with a name used
in marketing the product.  Maybe "MUCSE" is the name under which
Wuxi Micro Innovation Integrated Circuit Design Co.,Ltd markets
products?
