[netdrvr] irq handler minor cleanups in several drivers
* use irq_handler_t where appropriate * no need to use 'irq' function arg, its already stored in a data struct * rename irq handler 'irq' argument to 'dummy', where the function has been analyzed and proven not to use its first argument. * remove always-false "dev_id == NULL" test from irq handlers * remove pointless casts from void* * declance: irq argument is not const * add KERN_xxx printk prefix * fix minor whitespace weirdness Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
