Subject: [PATCH] pata-rb532-cf: platform_get_irq() failure ignored
Date: Tue, 03 Mar 2009 14:04:26 +0100	[thread overview]
Message-ID: <49AD2ADA.5030109@gmail.com> (raw)

------------------------------>8-------------8<---------------------------------
platform_get_irq() can return -ENXIO, but since 'irq' is an unsigned int, it
does not show when the IRQ resource wasn't found.
