Subject: [M68KNOMMU]: use setup_irq() in ColdFire simple timer
Date: Fri, 27 Jul 2007 01:09:00 +1000 [thread overview]
Message-ID: <200707261509.l6QF90EQ004063@goober> (raw)
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.
