[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (8/9)
Kill all uses of i2c_is_isa_adapter except for the hybrid drivers (it87, lm78, w83781d). The i2c-isa adapter not being registered with the i2c core anymore, drivers don't have to fear being erroneously attached to it. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
