#1735784 — Re: [PATCH v1] usb: host: Implement workaround for Erratum A-007463

The Subject: line should specify which type of USB host controller the
patch is for.  The kernel contains lots of different USB host
controller drivers.  How are we supposed to know that Erratum A-007463
applies to dwc3 xHCI controllers?

The Subject: line should say something like:

[PATCH v1] USB: host: dwc3: Implement workaround for Erratum A-007643

If we're talking about a dwc3 implementation, we need a quirk flag on
dwc3 core to be passed down to the xhci-plat device, like every other
quirk on this controller.

I also need a reference to SNPS stars ticket that talks about this problem.
