Subject: hwmon: (w83795) Move files removal to a separate function
X-Git-Tag: v2.6.37-rc1~59^2~44
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=2fa09878ba1dc458b8cb6e9c8fbc8f2e5401d2b2;p=net-next-2.6.git

hwmon: (w83795) Move files removal to a separate function

Sysfs files must be removed on device removal but also when device
registration fails. Move the code to a separate function to avoid
code redundancy.
