[PATCH 9/17] drivers/char/{synclink,tpm}: irq handler cleanups

[Jeff Garzik]

commit 81ccec23142e4fe42b3f72faecccb7b64f84007e
Author: Jeff Garzik <jeff@xxxxxxxxxx>
Date:   Fri Oct 19 19:27:19 2007 -0400

    drivers/char/{synclink,tpm}: irq handler cleanups
    
    * no need to use 'irq' function arg
    
    * delete pointless test, pointless casts
    
    * add KERN_xxx prefixes where appropriate
