Date: Thu, 26 Jan 2012 12:08:41 +0100 From: "Henrik Rydberg" <rydberg@...omail.se> To: Guenter Roeck <guenter.roeck@...csson.com> Cc: Jean Delvare <khali@...ux-fr.org>, lm-sensors@...sensors.org, linux-kernel@...r.kernel.org, Henrik Rydberg <rydberg@...omail.se> Subject: [PATCH] applesmc: Silence uninitialized warnings 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.
