Subject: [PATCH v6 01/14] mfd: da9063: Replace regmap_add_irq_chip with devm counterpart

Use devm_regmap_add_irq_chip() instead of plain regmap_add_irq_chip(),
which removes the need for da9063_irq_exit() altogether and also
fixes a bug in da9063_device_init() where the da9063_irq_exit() was
not called in a failpath.
