Subject: [PATCH] iio: accel: dmard10: convert probe to device-managed functions
Date: Wed, 30 Jun 2021 15:15:09 +0300 [thread overview]
Message-ID: <20210630121509.653717-1-aardelean@deviqon.com> (raw)
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.
