Commit 2f1c2b81 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86

Pull x86 platfrm driver fixes from Matthew Garrett:
 "Some trivial patches that fix wifi on some Lenovos and avoid a
  potential memory corruption issue on some Panasonics, plus two
  straightforward new drivers that touch no existing code."

* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
  panasonic-laptop: avoid overflow in acpi_pcc_hotkey_add()
  acer-wmi: No wifi rfkill on Lenovo machines
  Fujitsu tablet extras driver
  x86: Add amilo-rfkill driver for some Fujitsu-Siemens Amilo laptops

This is a driver for tablets built by Fujitsu:
* Lifebook P1510/P1610/P1620/Txxxx
* Stylistic ST5xxx
* Possibly other Fujitsu tablet models
It adds support for the panel buttons, docking station detection,
tablet/notebook mode detection for convertible and
orientation detection for docked slates.
