Subject: [PATCH v3 14/14] iio: hmc425a: simplify using
devm_regulator_get_enable()

[External]

Drop open-coded pattern: 'devm_regulator_get(), regulator_enable(),
add_action_or_reset(regulator_disable)' and use the
devm_regulator_get_enable() and drop the pointer to the regulator.
This simplifies code and makes it less tempting to add manual control
for the regulator which is also controlled by devm.

(I see that in this patch you are not using dev_err_probe(). Maybe some
consistency in the series and where applicable would be appropriate :))

I don't think the driver did originally print an error if regulator get or enable failed. I didn't want to add any new prints - just converted the existing ones to use dev_err_probe(). I believe adding new prints would've been somewhat unrelated change :)

Yours,
