m68knommu: use setup_irq() in ColdFire simple timer
Greg Ungerer [Thu, 26 Jul 2007 15:09:00 +0000 (01:09 +1000)]
Use setup_irq() instead of request_irq() to set up system timer
in ColdFire simple timer code. With the old m68knommu irq code this
was safe, but it is not now within the generic irq framework.
