X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cec87f1d2686057654e4565b8eaab4f539e9afca;p=linux-beck.git

usb: dwc2: gadget: check interrupts for all endpoints

Current code does not check endpoint 15 interrupt. Use number
of endpoint configured in hardware instead of the hardcoded value.
