First, reserved memory assigned with of_reserved_mem_device_init() is never released on driver removal or later probe failures. Second, the probe-time runtime PM resume used before reinitializing the regmap cache is unchecked, and a regmap_reinit_cache() failure skips the temporary PM put. Fix both issues with a devm reserved-memory release action and checked runtime PM resume handling.
