Subject: REGRESSION: Renesas USB host broken after commit d143825baf15

Hi,

the recent patch landed in 5.13.2 stable tree from the upstream commit
d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state")
seems causing a regression on a few machines, as reported on openSUSE
Bugzilla:
  https://bugzilla.opensuse.org/show_bug.cgi?id=1188485
  https://bugzilla.opensuse.org/show_bug.cgi?id=1188515

Reverting it on top of 5.13.3 fixed the problem, so it's likely the
cause.  Could you guys take a look?


thanks,

Takashi
