Re: [PATCH v2] usb: pci-quirks: abort xHCI handoff if MMIO is inaccessible

[Haowen Bai]

Hi Greg,

> Sorry, but I see no context here at all :(

Sorry for the missing context. The v2 patch is here:

https://patchew.org/linux/02C44DCEA968C75D%2B20260914022743.30852-1-calvin.bai%40ugreen.com/

It makes the xHCI early handoff abort when MMIO reads return all ones,
avoiding prolonged polling and soft lockups during PCI hotplug.

The v2 incorporates Lukas's suggestion to use PCI_POSSIBLE_ERROR()
and carries Mathias's Acked-by.

Could you please take this through your USB tree, or should it go
through Mathias's xHCI tree? I can resend the full patch if needed.

Thanks,
Haowen
