Subject: generic-adc-battery: Fix checking return value of request_any_context_irq
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5af092245a33965a4b089e8ba489c2db0f7db16;p=linux-beck.git

generic-adc-battery: Fix checking return value of request_any_context_irq

On failure, request_any_context_irq() returns a negative value. On
success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.
