drivers/hwmon/nct6775-platform.c:199:9: sparse: unsigned char drivers/hwmon/nct6775-platform.c:199:9: sparse: void
This is getting tiresome. Every driver using outb() on m68k will experience that "problem". As far as I can see, it is caused by #define out_8(addr,b) (void)((*(__force volatile u8 *) (unsigned long)(addr)) = (b)) in arch/m68k/include/asm/raw_io.h. I have no idea what the "(void)" is for, but removing it "fixes" the problem. Either case, this is not a problem with the nct6775 driver, nor is it a new problem. Guenter
