I can only agree. I was skeptical that reverting this commit would fix
the issue but it does.

Are you suggesting you want to fix those messages ? I am sorry if I
was not clear before, those messages are always present even on a
"good" build.
The issue is that on a "bad" build they hold back the boot process
from continuing. USB functionality is never affected.

I am building with a config based on my current distribution, Arch
Linux, with olddefconfig. A quick grep for the values found in the
commit returns the following :
CONFIG_USB_XHCI_PCI=y
CONFIG_USB_XHCI_PCI_RENESAS=m
