[PATCH v2 1/2] mfd: da9063: Get irq base dynamically before registering device
From: Dmitry Lavnikevich
Date: Fri Nov 21 2014 - 10:29:26 EST
After registering mfd device with proper irq_base
platform_get_irq_byname() calls will return VIRQ instead of local IRQ.
This fixes da9063 rtc registration issue:
da9063-rtc da9063-rtc: Failed to request ALARM IRQ 1: -22
