From 32ee56e306b09568619466efe109ab9722e89245 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 13 May 2015 15:06:12 -0300 Subject: [PATCH] iio: orientation: hid-sensor-incl-3d: Fix memory leak in probe() 'channels' is allocated via kmemdup and it is never freed in the subsequent error paths. Use 'indio_dev->channels' directly instead, so that we avoid such memory leak problem.
