Sebastian Andrzej Siewior 61d58242f6 usb: dwc3: gadget: replace mdelay with udelay in the busy loop ... There are two spots where we wait until the HW finishes processing a certain command. Initially we had a few problems and we used 500ms as a limit to be on a the safe side. Paul Zimmerman mentioned this is little too much. After a debugging session, we noticed that we hardly ever go over 20us and didn't pass 30usec so far. Using mdelay() seems way overloaded. Giving the current numbers 500usec as the upper limit is more than enough. Should it ever timeout then something is definitely wrong. While here, also replace the type with u32 since long does not really fit here.
