From e19166d5df10be0ea404c4e346cf6be93bfb1d63 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 18 Apr 2008 19:22:52 -0400 Subject: [SCSI] aha152x, eata, u14-34f: minor irq handler cleanups - remove pointless casts from void* - remove needless references to 'irq' function argument, when that information is already stored somewhere in a driver-private struct. - where the 'irq' function argument is known never to be used, rename it to 'dummy' to make this more obvious - remove always-false tests for dev_id==NULL - remove always-true tests for 'irq == host_struct->irq' - replace per-irq lookup functions and tables with a direct reference to data object obtained via 'dev_id' function argument, passed from request_irq() This change's main purpose is to prepare for the patchset in jgarzik/misc-2.6.git#irq-remove, that explores removal of the never-used 'irq' argument in each interrupt handler.
