hwmon: (smsc47b397) Fix compiler warning
Some configurations produce the following compiler warning: drivers/hwmon/smsc47b397.c: In function 'smsc47b397_init': drivers/hwmon/smsc47b397.c:385: warning: 'address' may be used uninitialized in this function While this is a false positive, it can easily be fixed by overloading the return value from smsc47b397_find with both address and error return code (the address is an unsigned short and thus never negative). This also reduces module size by a few bytes (64 bytes for x86_64). Cc: Mark M.
