Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86
Pull x86 platform driver updates from Matthew Garrett:
"Nothing overly exciting here - a couple of new drivers that don't do a
great deal, along with some miscellaneous fixes and a couple of small
feature enablement patches"
* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
x86 platform drivers: fix gpio leak
toshiba_acpi: Add dependency on SERIO_I8042
asus-nb-wmi: set wapf=4 for ASUSTeK COMPUTER INC. 1015E/U
Add trivial driver to disable Intel Smart Connect
Add support driver for Intel Rapid Start Technology
hp-wmi: add supports for POST code error
asus-wmi: control wlan-led only if wapf == 4
drivers/platform/x86/intel_ips: Convert to module_pci_driver
asus-nb-wmi: ignore ALS notification key code
asus-wmi: append newline to messages
x86: asus-laptop: fix invalid point access
x86: msi-laptop: fix memleak
amilo-rfkill: Add dependency on SERIO_I8042
dell-laptop: fix error return code in dell_init()
hp-wmi: Enable hotkeys on some systems
