The irq_of_parse_and_map() returns 0 on failure, not a negative ERRNO.

d530e9943d irqchip/aspeed-scu: Replace update_bits with write_bits. 
commit 8958389681 upstream.

The interrupt status bits are cleared by writing 1, we should force a
write to clear the interrupt without checking if the value has changed.

04f605906f irqchip: Add Aspeed SCU interrupt controller 
The Aspeed SOCs provide some interrupts through the System Control
Unit registers. Add an interrupt controller that provides these
interrupts to the system.
