Re: [PATCH v2] usb: gadget: mv_u3d: request_irq() after initializing UDC

Nadezda Lutovinova [off-list ref] writes:

If IRQ occurs between calling  request_irq() and  mv_u3d_eps_init(),
then null pointer dereference occurs since u3d->eps[] wasn't
initialized yet but used in mv_u3d_nuke().

The patch puts registration of the interrupt handler after
initializing of neccesery data.

Found by Linux Driver Verification project (linuxtesting.org).
