extcon: adc-jack: Fix an error handling path in 'adc_jack_probe()'
[ Upstream commit bc84cff2c92ae5ccb2c37da73756e7174b1b430f ]
In some error handling paths, a call to 'iio_channel_get()' is not balanced
by a corresponding call to 'iio_channel_release()'.
This can be achieved easily by using the devm_ variant of
'iio_channel_get()'.
This has the extra benefit to simplify the remove function.
