Subject: [Regression] usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas

Hi Daniel,

A kernel bug report was opened against Ubuntu [0].  It was found the
following patch introduced the regression:

da9970668948 ("usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas uPD720201")

The bug reporter claims there is a typo in the patch that caused the
regression.  I built a test kernel with a change to the suspected typo
and the bug reporter claims it resolved the regression.  My test kernel
had the following change:

-                       pdev->device == 0x0014)
+                       pdev->device == 0x0015)

I was hoping to get your feedback, since you are the patch author.  Do
you think this is an actual typo, or maybe there really needs to be two
