   Allocate IRQs for a device with the MSI capability.
   This function returns a negative errno if an error occurs.  If it
   is unable to allocate the number of interrupts requested, it returns
   the number of interrupts it might be able to allocate.  If it successfully
   allocates at least the number of interrupts requested, it returns 0 and
   updates the <em class="parameter"><code>dev</code></em>'s irq member to the lowest new interrupt number; the
   other interrupt numbers allocated to this device are consecutive.
