202e4851f8 hwmon: (w83l786ng) Convert to devm_hwmon_device_register_with_groups
Use ATTRIBUTE_GROUPS macro and devm_hwmon_device_register_with_groups() to
simplify the code a bit.

a8d4d82e50 hwmon: (w83l786ng) Report correct minimum fan speed
Current code is buggy, it shows the current fan speed as minimum fan speed.
Fix up show_fan_reg macro to correctly report fan and fan_min speed.

33a7ab91d5 hwmon: (w83l768ng) Fix fan speed control range
The W83L786NG stores the fan speed on 4 bits while the sysfs interface
uses a 0-255 range. Thus the driver should scale the user input down
to map it to the device range, and scale up the value read from the
device before presenting it to the user. The reserved register nibble
should be left unchanged.

cf7559bc05 hwmon: (w83l786ng) Fix fan speed control mode setting and reporting
The wrong mask is used, which causes some fan speed control modes
(pwmX_enable) to be incorrectly reported, and some modes to be
impossible to set.

SENSORS_LIMIT and the generic clamp_val have the same functionality,
and clamp_val is more efficient.

4101ece3a2 hwmon: Fix chip feature table headers
These got broken by recent patches fixing checkpatch warnings in these
drivers. The trick is that the patches themselves looked good, but the
source files after applying them do not. That's why I am not a big fan
of using tabs inside comments.

file. Fix that, and also fix one driver which was including the header

90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.
