From 72565224609a23a60d10fcdf42f87a2fa8f7b16d Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Fri, 20 Jan 2012 19:48:28 -0300 Subject: [PATCH] [media] cxd2820r: sleep on DVB-T/T2 delivery system switch Fix bug introduced by multi-frontend to single-frontend change. It is safer to put DVB-T parts sleeping when auto-switching to DVB-T2 and vice versa. That was original behaviour.
