From: Michael Krufky Date: Sat, 8 Dec 2007 20:06:30 +0000 (-0300) Subject: V4L/DVB (6783): tuner: combine set_tv_freq and set_radio_freq into a single set_param... X-Git-Tag: v2.6.25-rc1~1235^2~221 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c7919d520f4c9a064ae14bc4dd170c4c12ead2af;p=karo-tx-linux.git V4L/DVB (6783): tuner: combine set_tv_freq and set_radio_freq into a single set_params method We can tell whether we are tuning television or radio by testing for struct analog_parameters *params->mode == V4L2_TUNER_RADIO There is no longer any need for separate set_tv_freq and set_radio_freq functions in the analog tuner demodulator modules.
