Hello, An error was found in the code of the drivers/hwmon/nct7802.c file. A macro mismatch on line 49 #define SMARTFI_EN_SHIFT(x) ((x) %2 *4)of the chip documentation dated 02.2020 in Table No. 7.2.95 "Temperature to Fan mapping Relationships Register".
I suggest this simple variant: #define SMARTFI_EN_SHIFT(x) (((x)==0)?0:(((x)==1)?5:2))
