Third version of a hwmon driver to monitor the fan's rpm on Microsoft
Surface devices, originally submitted in [1], v2 at [2]. All changes since
v2 are incorporating feedback, cleaning up and simplifying the module.
Changes in v3:
- Removed type and attr checks in read and is_visible.
- Removed assigning sdev to ssam_device drvdata.
- Propagate return from __ssam_fan_rpm_get.
- Renamed hwmon chip name from 'fan' to 'surface_fan'.
- Removed unnecessary platform_device header.
Changes in v2:
- Removed all unsupported sysfs attributes from the hwmon driver, leaving
the fan input as the only supported attribute.
