Wei Yongjun 7bdeb7f52b irqchip/aspeed-i2c-ic: Fix return value check in aspeed_i2c_ic_of_init() 
In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test..

Brendan Higgins f48e699ddf irqchip/aspeed-i2c-ic: Add I2C IRQ controller for Aspeed 
The Aspeed 24XX/25XX chips share a single hardware interrupt across 14
separate I2C busses. This adds a dummy irqchip which maps the single
hardware interrupt to software interrupts for each of the busses.
