It works, with no apparent issue. Scanning is OK, tuning is OK. I can't test signals below 600MHz at the moment, but I will try (possibly VHF too) in a couple of days, just to be sure about the frequency handling code. Also tried removing the USB stick while playing a stream; the devices were correctly removed when the user space apps closed them. In my (user) opinion this driver is ready to be merged. I actually fixed some trivial compilation issues in the driver. --- a/linux/drivers/media/common/tuners/mc44s80x.c 2009-01-05 12:38:11.000000000 +0100 +++ b/linux/drivers/media/common/tuners/mc44s80x.c 2009-01-05 16:12:59.000000000 +0100 @@ -470,12 +470,12 @@ mc44s80x_set_power(state, 0); /* disable powerdown */ printk(KERN_WARNING "mc44s80x: MC44S80x get Device ID\n"); - err = i2c_transfer(state->i2c, &msg, 1); + err = i2c_transfer(state->i2c, msg1, 1); if (err != 1) { printk(KERN_WARNING "mc44s80x: Write error\n"); goto exit; } - err = i2c_transfer(state->i2c, &msg, 1); + err = i2c_transfer(state->i2c, msg2, 1); if (err != 1) { printk(KERN_WARNING "mc44s80x: Read error, Reg=[0x%02x]\n", TUNER_ADDR + 1); @@ -495,7 +495,7 @@ return 0; unk: printk(KERN_WARNING "mc44s80x: Chip with unknown Revision ID " - "(0x%02x)\n", __func__, id); + "(0x%02x)\n", id); goto out; exit: if (fe->ops.i2c_gate_ctrl) @@ -512,7 +512,7 @@ int err = 0; printk(KERN_WARNING "mc44s80x: Trying to attach to Bus @ 0x%p\n", i2c); - state = kzalloc(sizeof(struct mc44s80x_state), GFP_KERNEL)); + state = kzalloc(sizeof(struct mc44s80x_state), GFP_KERNEL); if (state == NULL) { err = -ENOMEM; goto exit; > Thanks, > Jochen Thanks to you. -- Roberto Ragusa mail at robertoragusa.it _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
