A CMDQV left enabled with a\nlatched error across a kexec fires the IRQ as soon as it is requested, and\ntegra241_cmdqv_isr() then walks the uninitialized cmdqv->vintfs array.\n\nRequest the IRQ only after cmdqv->vintfs is allocated and zeroed, so that\na latched interrupt firing early runs the ISR against a valid array of NULL\nslots that it safely skips."
