2008-05-26tuner: Do not alter i2c_client.nameMichael Krufky
The tuner driver used to change i2c_client.name for its own needs, but it really shouldn't, as this field is used by i2c-core to do the device/driver matching. So, create and use a separate field for the tuner driver needs. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-18i2c: Convert remaining new-style drivers to use module aliasingJean Delvare
Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-14V4L/DVB (7893): xc5000: bug-fix: allow multiple devices in a single systemMichael Krufky
The current code passes a context pointer in the xc5000_config struct. This context pointer is used in the tuner_callback function, used to reset the device after firmware download. The xc5000_config struct is a static structure, whose .priv member was being assigned before calling xc5000_attach(). If there are more than one of the same device type installed on a single system, the last one to assign xc5000_config.priv will "win", and all others will cease to function properly. This patch passes the context pointer in xc5000_attach() rather that storing it within the static struct xc5000_config.

2008-04-26V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug enabledMauro Carvalho Chehab
set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't reported. This patch changed set_addr printk to print a message only if set_addr is wrong. It also fix printk at set_type, since, if an attach were failing, nothing were reported. With the current code, working or not, a call to set_addr will produce a debug printk. also, set_type() were producing a false error message on tuner_xc2028, since it were requesting for setting a frequency on a place where firmware name weren't set yet.

2008-04-24V4L/DVB (7399): Removes video_dev from tuner-xc2028 config structMauro Carvalho Chehab
The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data, uses this instead. This parameter were used also as a magic number to idenfity if two drivers are trying to register the same xc3028 tuner. This occurs with boards with DVB support, where both DVB and V4L drivers will share the same tuner. Instead of using the algo_data as a private number, after this patch, the driver will use i2c_adap->dev, with seems more consistent. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
