3.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>
commit 12adef5b49e98eb181b4163c36e2998169e1379b upstream.
In probe the driver queued delayed work for cable detection and
returned the result of queue_delayed_work() call. However the return
value of queue_delayed_work() does not indicate an error and in normal
condition it returns true which means successful work queue.
This effectively resulted in probe failure:
[ 2.088204] max14577-muic: probe of max77836-muic failed with error 1
