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(). [Compiled tested only] Acked-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
