Greetings,
This patch updates the adm9240 driver:
o remove half-bit offset from scaled zero value
o remove i2c read/write wrappers
o convert kmalloc + memset calls to kzalloc
o convert temperature, voltage and fan accessors to dynamic sysfs callbacks
which shrinks driver memory footprint from 16472 to 14264 bytes.
Depends on adm9240 whitespace cleanup patch submitted earlier.
Run tested.
