Re: [PATCH v9 3/5] usb: dwc3: qcom: Add helper functions to enable,disable wake irqs

[Matthias Kaehlcke]

Hi Felipe,

This patch is (supposedly) an improvement regardless of whether the rest of
the series lands or not. It hasn't changed in the last iterations nor did
it receive any comments. Can this be landed rather than carrying it around
until the rest of the series is ready?

Thanks

Matthias
