alpha: irq clean up
Stop touching irq_desc[irq] directly, instead use accessor functions provided. Use irq_has_action instead of directly testing the irq_desc. Tested-by: Michael Cree <mcree@orcon.net.nz> Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: Matt Turner <mattst88@gmail.com>
