[PATCH v3 03/11] hwmon: (amc6821) Rename fan1_div to fan1_pulses

[Guenter Roeck <linux@roeck-us.net>]

The chip does not have a fan divisor. What it does have is a configuration
to set either 2 or 4 pulses per fan rotation. Rename the attribute to
reflect its use. Update documentation accordingly.
