Blackfin arch: Allow a gpio pin be requested both as gpio and irq.
[Mike Frysinger <vapier.adi@gmail.com>: - use KERN_NOTICE when using gpios as both irq and non rather than KERN_ERR - embedded newlines in printk() does not fly] Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
