From a69d978be8a068944466e776de87527fb104a878 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Mon, 15 Nov 2010 19:35:14 +0000 Subject: C and other Super I/O cosmetic fixes. - Random coding style, whitespace and cosmetic fixes. - Consistently use the same spacing and 4-hexdigit port number format in the pnp_dev_info[] arrays. - Drop dead/unused code and less useful comments. - Add missing "(C)" characters and copyright years. - Shorten and simplify some code snippets. - Use u8/u16/etc. everywhere.
