[PATCH 1/3] IDE: Coding Style fixes to drivers/ide/ide-cd.c

From: Paolo Ciarrocchi
Date: Sun Feb 24 2008 - 16:10:55 EST

Before:
total: 43 errors, 66 warnings, 2183 lines checked

After:
total: 0 errors, 36 warnings, 2192 lines checked

I didn't (and I don't plan to) fix the warnings:
WARNING: line over 80 characters
