From 5f49ef8e8cefe0a95948b4270db28507c1c287d4 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 22 Sep 2005 21:50:47 +0200 Subject: [PATCH] [PATCH] i2c-viapro: Coding style fixes Before I go on cleaning up and improving the i2c-viapro driver, let's fix all the coding style issues: mostly trailing white space, and spaces used where tabs should be.
