Hello Matthew,

may I request that you include the patch

      sony-laptop: fully enable SNY controlled modems

for 3.8 as well?  I'd even like it to go to stable if you and Mattia
agree.

My rationale is:

Making the driver set the same 3 bits which Windows set is obviously a
bug fix and not a new feature.  The fix is a simple oneliner, and is
required for a number of "newer" laptops, where newer in this case
includes most of 2012.  Without this fix rfkill will fail silently,
causing the wwan module to appear to be available but not working
because the radio is disabled.  This causes very hard to debug problems
for end users and distributions. Ref the bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=47751

See also the thread at http://ubuntuforums.org/showthread.php?t=2040205
for an example of the problems this bug causes for end users.

Thanks,
Bjørn
