Many thanks. I see this _superseded_ patch version (and apparently the whole series) present on your "next" branch, as well as on linux-next: https://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git/commit/?h=next&id=8b20d00f0f08 https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=8b20d00f0f08 The most recent v5 version of this series has been recently pushed to (not yet visible in upstream): https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/log/?h=usb-testing -- Best Regards, Eugeniu
