The check for bounded gadget driver in dwc3_gadget_start() was to
prevent going through the initialization again without any cleanup. With
a recent update, the UDC framework guarantees this won't happen while
the UDC is started. Also, this check doesn't prevent requesting threaded
irq to the same dev_id, which will mess up the irq freeing logic. Let's
remove it.

What "recent update" caused this?  Is this a fix for something that
needs to be backported?  If so, can you provide a "Fixes:" tag on here?
Or is this just a general cleanup that is good to do now.

It's general cleanup. The "recent update" is not in mainline yet but on
your "usb-next" branch so I'm not sure how to properly reference it.

But here's the commit on your branch I was referring to: 49d08cfc7830
("usb: udc: core: Introduce started state")

No need to backport this because it doesn't fix anything.

Thanks,
