[PATCH v2 6/6] usb: dwc3: dwc3-omap: Disable/Enable only wrapper interrupts in prepare/complete

From: George Cherian
Date: Mon May 19 2014 - 04:35:18 EST


The dwc3 wrapper driver should not be fiddling with the core interrupts.
Disabling the core interrupts in prepare stops xhci from proper operation.
So remove disable/enable of core interrupts from prepare/complete.
