Subject: [ 012/100] sony-laptop: fully enable SNY controlled modems

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mattia Dongili <malattia@...ux.it>

commit 3ec1c3983d73b1e3d4cfd72afab94c34eceafe8a upstream.

The call to handlers 0x124 and 0x135 (rfkill control) seems to take a
bitmask to control various states of the device. For our rfkill we need
a fully on/off. SVZ1311Z9R/X's LTE modem needs more bits up.
