From e2f63d9ba51efe8930bf1c952c66b971047d355d Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 4 Feb 2011 11:15:21 -0300 Subject: [PATCH] [media] tuner-core: do the right thing for suspend/resume Power down tuners at suspend. At resume, if the tuner is in standby, calls set_mode, that will turn it on and set the latest frequencies.
