The Kconfig symbol names were changed, the target object has changed,
the module filename has changed.

A submenu was added, the USB support is not enabled by default.

None of the above fixed any bug, it just makes unnecessary changes
that are inappropriate this late in a kernel development cycle.

If a bug needed to be fixed, it would have been as simple as adding
the new object file for smssdio.o , and the old
DVB_SIANO_SMS1XXX_SMS_IDS section could have been removed without
changing everything.

I think this is ridiculous to slip in at the last moment, but I would
have had no complaints seeing this in the next merge window.

What is the point of a "merge window" if you let people make such
changes as this right before a kernel is released.

Maybe it all works, maybe it doesnt.  I know I personally am not going
to test this before September fifth, the day Linus plans to release
2.6.31. ..  And even if I do find a problem, how should I know that
the powers that be will act on a regression fix in a timely manner?

Apologies to the users of this driver -- I am not interested anymore.
My time is better spend working on my own code.

On the bright side, I have some really interesting stuff coming.  I
will be posting some RFC's this week that will help to alleviate some
long-standing problems within the media subsystems.  I won't stress
over Siano's driver any longer -- this gives me more time to focus on
the really cool fun stuff :-)

If the kernel's support for this driver becomes broken again, users
can just use the driver that I have posted on kernellabs.com

Cheers,

Mike
