Pull regulator fixes from Mark Brown: "Two driver fixes, one fixing the mapping of interrupts on da9055 (which previously wouldn't have worked at all) and a fix for reference counting OF nodes in the max14577 driver" * tag 'regulator-v3.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: da9055: Remove use of regmap_irq_get_virq() regulator: max14577: Add missing of_node_put
