Matti Vaittinen 22b4277641 iio: ad7292: Prevent regulator double disable
The ad7292 tries to add an devm_action for disabling a regulator at
device detach using devm_add_action_or_reset(). The
devm_add_action_or_reset() does call the release function should adding
action fail. The driver inspects the value returned by
devm_add_action_or_reset() and manually calls regulator_disable() if
adding the action has failed. This leads to double disable and messes
the enable count for regulator.

Do not manually call disable if devm_add_action_or_reset() fails.
