From fbe4a29f2f6523b8b839debb19baa49461a302be Mon Sep 17 00:00:00 2001 From: Istvan Varga Date: Fri, 3 Jun 2011 10:11:48 -0300 Subject: [PATCH] [media] xc4000: code cleanup This is the first of a set of patches that update the original xc4000 sources to my modified version. It removes some unused code, and makes a few minor formatting changes.
