[lm-sensors] [PATCH 2.6] I2C: Separate non-i2c hwmon drivers from

[khali@linux-fr.org (Jean Delvare)]

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.
