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.
