Subject: hwmon: (f71882fg) Fix fan_to/from_reg prototypes
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2f650631b3710622666367474b5475ff81ba486e;p=linux-beck.git

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.
