[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)
Call the ISA chip drivers detection function directly instead of relying on i2c_detect. The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
