hwmon: Add individual alarm files to 4 drivers
hwmon: Add individual alarm files to 4 drivers Add individual sysfs files for all f71805f, lm63, lm83 and lm90 alarm and fault conditions. This is a requirement for the planned chip-independent libsensors. Almost all other hwmon drivers will need the same improvement.
