e95fd518d0 hwmon: (w83627hf) Use request_muxed_region for Super-IO accesses
Super-IO accesses may fail on a system with no or unmapped LPC bus.

Also, other drivers may attempt to access the LPC bus at the same time,
resulting in undefined behavior.

Use request_muxed_region() to ensure that IO access on the requested
address space is supported, and to ensure that access by multiple drivers
is synchronized.

cb202bb8b3 hwmon: (iio_hwmon) Simplify attr.name generation in iio_hwmon_probe()
Since every call to devm_kasprintf() in the switch statement is mostly
the same, we can move all of the shared code outside and capture
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.
