[SCSI] initio: Convert into a real Linux driver and update to modern style
This is a mix of a grand clean up I did and a reworking of the hotplug support by Christoph. In testing it works as well as the previous code did (that is -quite badly-) but we can now read it and as it settles in actually debug the long standing problems it shares with the old driver. Signed-off-by: Alan Cox <alan@redhat.com> From Christoph: removal of the BSD license is also fine with me, but should really get a mention in the changelog aswell. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
