From d377aba193111419341fabaec6cab92df25e1b28 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 19 Oct 2017 19:05:59 +0200 Subject: [PATCH] thermal/drivers/generic-iio-adc: Switch tz request to devm version Everything mentionned here: https://lkml.org/lkml/2016/4/20/850 This driver was added before the devm_iio_channel_get() function version was merged. The sensor should be released before the iio channel, thus we had to use the non-devm version of thermal_zone_of_sensor_register(). Now the devm_iio_channel_get() is available, do the corresponding change in this driver and remove gadc_thermal_remove().
