aha152x: debug output update and whitespace cleanup
Remove all uncommented debugging code and move all printk() statements over to dev_printk(). And while we're at it we should be doing a whitespace cleanup, too. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Robert Elliott <elliott@hp.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
