Subject: [PATCH] soc: qcom: smd: Request irqs after parsing properties
Date: Tue,  9 Aug 2016 17:42:55 -0700	[thread overview]
Message-ID: <1470789775-5517-1-git-send-email-bjorn.andersson@linaro.org> (raw)

The code exectued by the interrupt handler depends on the values parsed
after requesting the irq, just to be save we should therefor move the
request_irq() call to be done after parsing the properties.
