usb: dwc2: gadget: don't overwrite DCTL register on NAKEFF interrupts When receiving GINTSTS_GINNAKEFF or GINTSTS_GOUTNAKEFF interrupt, DCTL will be overwritten with DCTL_CGOUTNAK or DCTL_CGNPINNAK values. Instead of overwriting it, write only needed bits. It could cause an issue if GINTSTS_GINNAKEFF or GINTSTS_GOUTNAKEFF interrupt is received after dwc2 disabled pullup by writing DCTL_SFTDISCON bit. Pullup will then be re-enabled whereas it should not. Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Gregory Herrero <gregory.herrero@intel.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
