From dde898fba89069f78be1d0174f5184dc939cce5f Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Tue, 26 Jul 2016 09:47:09 +0200 Subject: [PATCH] hwmon: (iio_hwmon) fix memory leak in name attribute commit 5d17d3b4bbf3becb89fd48b74340a50a39736f6d upstream. The "name" variable's memory is now freed when the device is destructed thanks to devm function.
