Subject: [PATCH v2 2/2] iio: light: adjd_s311: convert probe to device-managed functions
Date: Mon,  5 Jul 2021 10:14:56 +0300	[thread overview]
Message-ID: <20210705071456.649659-2-aardelean@deviqon.com> (raw)
In-Reply-To: <20210705071456.649659-1-aardelean@deviqon.com>

Now that the driver's buffer is stored on the adjd_s311_data private
object, the driver is a simple conversion to use only device-managed
functions in the probe.

The iio_triggered_buffer_setup() and iio_device_register() functions are
the only ones needing conversion.
And i2c_set_clientdata() is no longer required.
