Subject: [PATCH] sparc/xen/cxgb3: use irq_handler_t where appropriate


commit 21b1f26bf54a2ba1e4072db6dd01da128b1f66ef
Author: Jeff Garzik <jeff@...zik.org>
Date:   Fri Oct 19 03:12:20 2007 -0400

    [SPARC, XEN, NET/CXGB3] use irq_handler_t where appropriate
    
    Rather than hand-rolling our own prototype, make the code more
    future-proof by using the standard irq_handler_t typedef.
