From 7db98fe66be035494912b6b2c4e9c1e3abfedfe5 Mon Sep 17 00:00:00 2001 From: Istvan Varga Date: Sat, 4 Jun 2011 12:25:19 -0300 Subject: [PATCH] [media] xc4000: detect also xc4100 Added code to detect the XC4100 chip, which is presumably an analog-only "value" version of the XC4000. It is not sure, however, if any devices using this have actually been produced and sold, so the patch may be unneeded.
