platform-drivers-x86 for 4.4-1 

Various toshiba hotkey and keyboard related fixes and a new WMI driver. Several
 intel_scu_ipc cleanups and a locking fix. A spattering of small single fixes
 across various platforms.
 
 I was asked to pick up an OLPC cleanup as the driver appeared unmaintained and
 it seemed similar to what is maintained in platform/drivers/x86. I have included
 the patch and an update to the MAINTAINERS file.
 
 toshiba_acpi:
  - Initialize hotkey_event_type variable
  - Remove unneeded u32 variables from *setup_keyboard
  - Add 0x prefix to available_kbd_modes_show function
  - Change default Hotkey enabling value
  - Unify hotkey enabling functions
 
 toshiba-wmi:
  - Toshiba WMI Hotkey Driver
 
 intel_scu_ipc:
  - Protect dev member assignment on ->remove()
  - Switch to use module_pci_driver() macro
  - Convert to use struct device *
  - Propagate pointer to struct intel_scu_ipc_dev
  - Fix error path by turning to devm_* / pcim_*
 
 acer-wmi:
  - remove threeg and interface sysfs interfaces
 
 OLPC:
  - Use %*ph specifier instead of passing direct values
 
 MAINTAINERS:
  - Add drivers/platform/olpc to drivers/platform/x86
 
 sony-laptop:
  - Fix handling sony_nc_hotkeys_decode result
 
 intel_mid_powerbtn:
  - Remove misuse of IRQF_NO_SUSPEND flag
 
 compal-laptop:
  - Add charge control limit
 
 asus-wmi:
  - restore kbd led level after resume
