[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

[ Upstream commit 50f0f26e7c8665763d0d7d3372dbcf191f94d077 ]

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

Fixes: f48e699ddf70 ("irqchip/aspeed-i2c-ic: Add I2C IRQ controller for Aspeed")
