From 689f584b9858393809dc28046a7b51f9535d913d Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Wed, 30 Jun 2021 15:15:09 +0300 Subject: [PATCH] iio: accel: dmard10: convert probe to device-managed functions This is another simple conversion to device-managed functions, requiring the use of devm_iio_device_register() and moving the disabling of the device on a devm_add_action_or_reset() hook. The i2c_set_clientdata() can be removed, as the PM functions can work with just the device object, to obtain the i2c_client object.
