From: Hans de Goede Date: Fri, 9 Sep 2011 10:12:34 +0000 (+0200) Subject: hwmon/f71882fg: Add a f71882fg_create_fan_sysfs_files helper function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9af0794c63ab1fbced7aa6f9d918ee0f7e7c45e5;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git hwmon/f71882fg: Add a f71882fg_create_fan_sysfs_files helper function This is a preparation patch for not registering fan/pwm attributes for some fans (rather then register them for all or for none).
