From b22374544b981b82f7319a02e6b718fc796e9cfa Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 30 Dec 2010 08:01:01 -0300 Subject: [media] bttv-input: Add a note about PV951 RC When comparing lirc-i2c and ir-kbd-i2c/bttv-input logic, a difference was noticed. As lirc-i2c will be removed soon, store the difference on a comment inside ir-kbd-i2c, in order to preserve the knowledge we have about that remote controller.
