3.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dtor@xxxxxxxxxxxx>
commit 4c69f05eaa428e37890daf88b86a567ce615570b upstream.
Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.
