Re: [PATCH] usb: gadget: mv_u3d: Change functon call in mv_u3d_probe()

Hi,

(first of all, your subject could be a little more descriptive,
something like:

	usb: gadget: mv_u3d: request_irq() after initializing UDC

as that would better detail what you're doing)

this looks like an important bug fix, it probably deserves a stable tag
here. Which commit introduce this problem? Otherr than that, commits
looks good.
