[PATCH v1] mfd: intel_soc_pmic_core: Remove unnecessary function

From: Andy Shevchenko
Date: Mon Feb 20 2017 - 13:21:50 EST


Since commit 845c877009cf ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") I2C core assigns interrupt line to I2C slave
devices with regarding to GpioInt() resources.

There is no need to repeat this in the driver.
