From 3fd86d4898df10ee0b8884b5a31a512cb90f3362 Mon Sep 17 00:00:00 2001 From: Hirofumi Nakagawa Date: Tue, 4 Mar 2008 16:49:21 +0900 Subject: [PATCH] Remove duplicated unlikely() at IS_ERR() Some drivers have duplicated unlikely() macros. IS_ERR() already has unlikely() in itself. This patch cleans up such pointless codes although there is no real effect on the kernel's behaviour.
