From c52ae3d2794ee2a248245a9e5a26f717e1c401f5 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Fri, 13 Sep 2013 10:42:39 -0700 Subject: [PATCH] hwmon: (gpio_fan) Use error value returned from get_fan_speed_index() get_fan_speed_index() returns -EINVAL in case of errors, only to have it ignored and replaced with -ENODEV. Make it return -ENODEV and use it.
