Message-ID: <20141114220419.GA32497@dtor-ws>
Date: Fri, 14 Nov 2014 14:04:19 -0800
From: Dmitry Torokhov <dtor@...omium.org>
To: Ley Foon Tan <lftan@...era.com>
Cc: nios2-dev@...ts.rocketboards.org, linux-kernel@...r.kernel.org
Subject: [PATCH] nios2: fix error handling of irq_of_parse_and_map
Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.
Signed-off-by: Dmitry Torokhov <dtor@...omium.org>

Not tested, found by casual code inspection.
