Subject: Re: [PATCH 01/14] parport: return value of attach and
 parport_register_driver

1) We can't apply this patch on its own so this way of breaking up the
patches doesn't work.

2) I was thinking that all the ->attach() calls would have to succeed or
we would bail.  Having some of them succeed and some fail doesn't seem
like it will simplify the driver code very much.  But I can also see
your point.  Hm...

Minor comment:  No need to preserve the error code if there are lots
which we miss.  We may as well hard code an error code.  But that's a
minor thing.  Does this actually simplify the driver code?  That's the
more important thing.

regards,
dan carpenter
