From 8f1a58d0fccacb5d61aed8a63c3920c8acc155e7 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Tue, 7 Feb 2006 06:25:39 -0200 Subject: V4L/DVB (3277): Use default tuner_params if desired_type not available If a given tuner definition contains more than one tuner_params array members, it will try to select the appropriate tuner_params based on the video standard in use. If there is no tuner_params defined for the current video standard, it will select the default, tuner_params[0] Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/tuner-simple.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'drivers/media/video') diff --git a/drivers/media/video/tuner-simple.c b/drivers/media/video/tuner-simple.c index 2e680cf515a..61dd26a4397 100644 --- a/drivers/media/video/tuner-simple.c +++ b/drivers/media/video/tuner-simple.c @@ -163,6 +163,10 @@ static void default_set_tv_freq(struct i2c_client *c, unsigned int freq) continue; break; } + /* use default tuner_params if desired_type not available */ + if (desired_type != tun->params[j].type) + j = 0; + for (i = 0; i < tun->params[j].count; i++) { if (freq > tun->params[j].ranges[i].limit) continue; @@ -340,6 +344,9 @@ static void default_set_radio_freq(struct i2c_client *c, unsigned int freq) continue; break; } + /* use default tuner_params if desired_type not available */ + if (desired_type != tun->params[j].type) + j = 0; div = (20 * freq / 16000) + (int)(20*10.7); /* IF 10.7 MHz */ buffer[2] = (tun->params[j].ranges[0].config & ~TUNER_RATIO_MASK) | TUNER_RATIO_SELECT_50; /* 50 kHz step */ -- cgit v1.2.3
