Subject: [ 52/72] hwmon: (ads1015) Fix file leak in probe function

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <guenter.roeck@...csson.com>

commit 363434b5dc352464ac7601547891e5fc9105f124 upstream.

An error while creating sysfs attribute files in the driver's probe function
results in an error abort, but already created files are not removed. This patch
fixes the problem.
