I just tried to do a kernel compile on Debian Sid running kernel 5.2.
Downloaded 4.19.80 modded the quirks file, please find modded file
attached, and started the compile.
About an hour into it it fails with:
  CC      drivers/pci/quirks.o

I will try later with the latest 5.4-rc to see if the diff is
incompatible with 4.19.
Cheers.
