[PATCH 5.10 187/452] irqchip/aspeed-scu-ic: Fix irq_of_parse_and_map() return value

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

[ Upstream commit f03a9670d27d23fe734a456f16e2579b21ec02b4 ]

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

Fixes: 04f605906ff0 ("irqchip: Add Aspeed SCU interrupt controller")
