| Message-ID | <ubFuO-1I9-19@gated-at.bofh.it> |
The core driver should create and manage irq mappings instead of leaf drivers. This patch change to pass irq domain to devm_mfd_add_devices() and it will create mapping for irq resources automatically. And remove irq mapping in rtc driver since this has been done in core driver.

This way you propagate error properly. Thanks. -- Dmitry
