Subject: [patch] PCI: xilinx: testing wrong variable in setup irq function
Date: Tue, 9 Sep 2014 15:11:50 +0300	[thread overview]
Message-ID: <20140909121150.GD19760@mwanda> (raw)

We should be testing "hwirq" instead of "irq".  "irq" is unsigned so
it's never less than zero.  Also it's uninitialized.

Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
