[PATCH v1] USB: pci-quirks: Release EHCI device reference

| Message-ID | <[email protected]> |
for_each_pci_dev() holds a reference to the current device. The Intel
EHCI lookup breaks as soon as it finds a match, so the iterator does not
get a chance to drop that reference on its next iteration.
Release the reference before leaving the loop.
Fixes: 26b76798e050 ("Intel xhci: refactor EHCI/xHCI port switching")
