[PATCH 1/5] w83627ehf: Use hwmon_device_register_with_info and sensor groups

From: Peter Huewe
Date: Thu Mar 23 2017 - 09:01:58 EST


This patch replaces the old, deprecated call to hwmon_device_register
with the new hwmon_device_register_with_info and converts the whole
driver to the new hwmon interface using the hwmon_chip_info methods
and the attribute_group method.

All standard attributes were converted to the corresponding
hwmon_chip_info methods.
For some functions a hwmon channel to device channel conversion had to
be performed, e.g. hwmon_in_alarm has the info for alert_5 in channel 8.

All non-standard attributes are converted to the attribute_group method,
by
- adding them statically to the attribute_group if they are available
for all variants of devices supported by this driver
- adding them at probe time to the attribute_group if the availability
is depending on the actual chip type.
The appropriate count of entries was reserved.

As a pre-condition a reference to the sio_data structure was moved into
w83627ehf_data for easier retrieval of the information, since this is
much easier than trying to access the platform_data.

The driver is now much more "checkpatch clean" than it used to be, but
still not completely.
The conversion saves about 20k in the resulting .ko

Tested with a NCT6776F chip.

v2:
- converted to proper is_visible methods
- applied minor feedback of v1
