Subject: [PATCH] PCI: keystone: fix error handling of irq_of_parse_and_map
Date: Fri, 14 Nov 2014 14:19:03 -0800 [thread overview]
Message-ID: <20141114221903.GA38539@dtor-ws> (raw)
Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.
