SubjectRe: [RFT PATCH 0/4] usb: dwc2: Fixes and improvements
Hi Guenter,

Thank you for your work on this.

I tested this series on my usual setup, discussed on a previous thread (kenzo +
veyron), and your patchset fixes the crashes I was seeing.

I also did some testing with usb-storage, everything works as expected.

Best, Boris.
