Wrap a highly common idiom.  Makes the code easier to read, helps pave
the way for sdev->{id,channel} removal, and adds a token that can easily
by grepped-for in the future.

There are a couple sdev_id() and scmd_printk() updates thrown in as well.

In these drivers, scsi_remove_host() is called too late, at the point
it is called, the driver has already shut down too far to accept any
I/O that the shutdown might generate.  Any generated I/O actually
triggers a panic.

Fix this by calling scsi_remove_host() as early as possible and not
calling scsi_host_put() until just before we kfree the ahc_softc.

#include of C files and macro tricks to rename symbols are evil and just
cause trouble.  Let's doublicate the two functions as they're going to
go away soon enough anyway.

There's a spurious (and illegal since it's marked __exit) call to
ahc_linux_exit() in ahc_linux_init() which causes a double list
deletion of the transport class; remove it.

this patch is just a cross-port of the fixup for aic7xxx DT settings.
As the same restrictions apply for aic79xx also (DT requires wide
transfers) the dt setting routine should be modified equivalently.
And an invalid period setting will be caught by ahd_find_syncrate()
anyway.

since this card can support the setting, add it to the parameter list.

There's a slight problem in the way you've done the transport
parameters; reading from the variables actually produces the current
settings, not the ones you just set (and there's usually a lag because
devices don't renegotiate until the next command goes over the bus).  If
you set the bit immediately, you get into the situation where the
transport parameters report something as being set even if the drive
cannot support it.

I patched the driver to do it this way and also corrected a panic in the
proc routines.

This patch updates various scsi_transport_spi parameters with the actual
parameters used by the driver internally.
Domain Validation for all devices should now work properly.

This patch updates the aic79xx driver to take advantage of the
scsi_transport_spi infrastructure. Patch is quite a mess as some
procedures have been reshuffled to be closer to the aic7xxx driver.

This patch removes the busyq in aic79xx and uses the command-queue from

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
