hwmon: (applesmc) Silence uninitialized warnings
commit 0fc86eca1b338d06ec500b34ef7def79c32b602b upstream. Some error paths do not set a result, leading to the (false) assumption that the value may be used uninitialized. Set results for those paths as well. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
