This patch is whitespace damaged.

Please send the email to yourself and make sure it applies
correctly before resending to the lists.

If necessary, read Documentation/email-clients.txt

This patch is too big for the SCSI mailing list. We have a 400k limit.
Your patch is 292k, which would ordinarily be OK, but you attached it
twice (once inline and once as an attachment), which is why it's not
going through.

Why are you removing these adapters from the driver?

I agree with Dan, all these whitespace changes make the patch very hard
to read for the significant pieces; can't they be done separately?

Some of them, like this

Aren't even correct (last one introduces an extra spurious space).

Others, like this:

> + kfree((const void *)ver_addr);
[...]
> - kfree(ver_addr);

Are stylistically wrong: ver_addr is an unsigned char *; there's no
reason to cast it to anything before calling kfree (any pointer can be
passed without cast to a function taking a void *)

You do a lot of this spurious casting to void *; please don't:

Why assign to temp? You never refer to it again.

I'm sure there are other issues, but the massive code reformat changes
mean I probably missed them.
