From: Michael Krufky Date: Fri, 31 Aug 2007 02:00:43 +0000 (-0300) Subject: V4L/DVB (6136): dvb_frontend: add get_rf_strength function pointer to dvb_tuner_ops X-Git-Tag: v2.6.24-rc1~1463^2~136 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8fb3b9f7a9e0420150bf6cb8a3c20f45d372cce4;p=linux-2.6 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. This is an internal api addition -- userspace is not affected.
