hwmon: (f71882fg) Fix fan_to/from_reg prototypes
The RPM after conversion from / before conversion to a register value can be much more than 65535 (up to 1500000), so putting this into an u16 can cause overflows. This changes the functions to use an int to store / get RPM instead. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
