PATCH 1/1 genirq: devres: Fix testing return value of request_any_context_irq()

request_any_context_irq() returns a negative value on failure. It returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED on success. So fix testing return value of request_any_context_irq().

Fixes 0668d3065128 ("genirq: Add devm_request_any_context_irq()")
