50f0f26e7c irqchip/aspeed-i2c-ic: Fix irq_of_parse_and_map() return value
The irq_of_parse_and_map() returns 0 on failure, not a negative ERRNO.

046a6ee234 irqchip: Bulk conversion to generic_handle_domain_irq()
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

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..

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.
