From c7bec5aba52392aa8d675b8722735caf4a8b7265 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 6 Oct 2006 15:00:58 -0400 Subject: Various drivers' irq handlers: kill dead code, needless casts - Eliminate casts to/from void* - Eliminate checks for conditions that never occur. These typically fall into two classes: 1) Checking for 'dev_id == NULL', then it is never called with NULL as an argument. 2) Checking for invalid irq number, when the only caller (the system) guarantees the irq handler is called with the proper 'irq' number argument.
