Oneiric SRU (pre-stable): Fix Line out -> Speaker automute for Realtek

SRU Justification:

Fixes a blocks-hwcert bug.

Test case:

Take the Optiplex XE machine specified here:
http://bugs.launchpad.net/bugs/882693

Without this patch:
  - Internal Speaker is not muted when "Line Out" jack is plugged in
With this patch:
  - Internal Speaker is muted when "Line Out" jack is plugged in

Upstream status:
   Acked/reviewed by Takashi Iwai and on its way to 3.0 (and 3.1) stable.

Patch format documentation may need some clarification

This came up today on irc. Basically [1] and [2] talk about the format patches
should be submitted for sru and cves. [1] is much older and maybe needs to be
updated or hidden better.

But generally I can see one issue. But I am not sure whether this is just my
opinion, so I wanted to put it up for discussion.

When talking about the subject line of a patch, this can mean two places:
1. The subject line of the email containing the patch (or the cover letter)
2. The subject line of the actual patch

IMO, there are some things that make sense for 1. but not for 2., like
the target release, tags for sru / cve, or even the cve number (which is
in the body of the patch already). This seems to be even more confusing when the
patch is inlined as the email then has two subject lines (sort of):

Subject: [<releases>] (reason): <summary>

...

--- patch ---
Subject: [PATCH] [UBUNTU: [SAUCE] ...] <patch summary>

That is at least how I think is better because then one just can save the patch
and apply it. While if the patch itself contains the other tags, I would
manually remove them before applying.

In that light [2] sometimes would be confusing to me as it only speaks of patch
and subject. So, is the intention as I wrote it down? Then I would try to update
the wiki page accordingly... Should the older page be removed/updated?

Testing pool for Oneiric SRU

Hi,

As the Oneiric -proposed kernel has become available for testing, we're 
about to commence with it. We're proposing to use our new testing pool 
functionality which you may have heard about to reduce the number of 
systems we need to test while still providing maximum device coverage. 
In a previous mail, Marc showed you the list of components that we've 
proposed as 'important' for the purpose of including at least one of 
each different device of that type in the testing pool. This is the list 
as it stands:

https://docs.google.com/spreadsheet/ccc?key=0AphFraZYTghddElqTHl3NmZsWXVDYkMxcE5zX3EtR0E&hl=en_US#gid=0

and this is the testing pool it created:

https://docs.google.com/spreadsheet/ccc?key=0ApQ2JshzVOLydEtFOWxPZ2h6R3BhcDFDbnV4SHJuT1E

There is a link to the Ubuntu certification page for that system so you 
can have a look at which components it has. This is mainly for 
transparency.

As with Marc's email I would urge you to check the components on the 
first spreadsheet with an X next to them, as these are the ones that 
*are not* considered for the purposes of shrinking the testing pool. 
Marking one of them as important will allow the tool to include at least 
one system that includes each different component of that type and 
potentially *increase* the number of systems in the pool. The goal is to 
cover as much hardware as possible with a reasonably sized testing pool.

Thanks,

Have you also tried this laptop with Precise to make sure the 
"refactored automute for Realtek" still works ?

_And_ have you tested this patch for regressions on other platforms with 
Realtek codecs ?
