From 89c3bc78075042ae1f4452687f626acce06b3b21 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 28 Jun 2010 12:59:49 -0300 Subject: V4L/DVB: cx88: Let the user disable IR support It might be useful to be able to disable the IR support, either for debugging purposes, or just for users who know they won't use the IR remote control anyway. On many cards, IR support requires expensive polling/sampling which is better avoided if never needed.
