hwmon: (max6650) Drop call to thermal_cdev_update
The call to thermal_cdev_update() causes any fan connected to the chip
to stop immediately. If the thermal subsystem is not set up to actually
handle the chip as cooling device, the remains stopped until is is
restarted manually with a write to a sysfs attribute.
There is evidence that thermal_cdev_update() should only be called from
thermal governors, not from thermal cooling device drivers. Drop the call.

hwmon: (ina3221) Add voltage conversion time settings
The CONFIG register has two 3-bit fields for conversion time
settings of Bus-voltage and Shunt-voltage, respectively. The
conversion settings, along with averaging mode, allow users
to optimize available timing requirement.
This patch adds an 'update_interval' sysfs node through the
hwmon_chip_info of hwmon core. It reflects a total hardware
conversion time:
samples * channels * (Bus + Shunt conversion times)
Though INA3221 supports different conversion time setups for

is synchronized.

hwmon: (iio_hwmon) Simplify attr.name generation in iio_hwmon_probe()
Since every call to devm_kasprintf() in the switch statement is mostly

differencies with two helper variables. No functional change intended.

The new helper devm_platform_ioremap_resource() wraps
platform_get_resource() and devm_ioremap_resource() together.
Use it to simplify the code.
