[PATCH 3.14 008/110] extcon: max14577: Properly handle regmap_irq_get_virq error

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>

commit 369afd4ba22f5b8de0c9229b6e62b3f9e2207034 upstream.

The regmap_irq_get_virq may return 0 or -EINVAL on error. Fail the probe
in both situations.
