From 8fb3b9f7a9e0420150bf6cb8a3c20f45d372cce4 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Thu, 30 Aug 2007 23:00:43 -0300 Subject: V4L/DVB (6136): dvb_frontend: add get_rf_strength function pointer to dvb_tuner_ops Add get_rf_strength function pointer to dvb_tuner_ops, so that rf signal strength can be read directly from the tuner driver by the dvb demodulator driver and / or the analog tuning system.
