[RFC] [Maverick] UBUNTU: SAUCE: Add MODULE_ALIAS for Dell WMI module

[Leann Ogasawara]

Hi Mario,

We've been temporarily carrying an Ubuntu SAUCE patch (inlined at the
bottom), originally authored by yourself.  In the commit message you'd
noted that upstream was not in favor of applying this patch but instead
would prefer to wait for the WMI sysfs interface to be incorporated.  It
seems that this has now been added as of 2.6.33-rc1:

commit 1caab3c1a90be3aa4ec3599409d8fe044b077478

    wmi: Add support for module autoloading

I assume it is now safe for us to drop the temporary patch we've been
carrying that you had originally authored?  I see that acer-wmi already
dropped similar bits it was carrying:

commit 4d5f177caf1ef78f5e7eaee75b66b4d534445682
Author: Thomas Renninger <trenn at suse.de>
Date:   Fri Dec 18 15:29:22 2009 +0100

    acer-wmi, msi-wmi: Remove needless DMI MODULE_ALIAS
    
    Now that we have WMI autoloading
    the DMI matching is not needed anymore.

Thanks,
Leann

Subject: [PATCH] UBUNTU: SAUCE: Add MODULE_ALIAS for Dell WMI module

>From Mario Limonciello: Until the sysfs WMI interface is ready, there is no way
to automatically determine when to load dell-wmi.  The equivalent module for Acer
laptops, acer-wmi has a workaround in place to match on the DMI tables for the machine.
This type of solution works on for Dell as well and gets the module loading when necessary.

Upstream is not in favor of applying this patch, but rather waiting for the sysfs
interface to be ready. Until it is, this provides a solution to ensure machines that
support WMI hotkeys are functional.
