Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86: (88 commits) ips driver: make it less chatty intel_scu_ipc: fix size field for intel_scu_ipc_command intel_scu_ipc: return -EIO for error condition in busy_loop intel_scu_ipc: fix data packing of PMIC command on Moorestown Clean up command packing on MRST. zero the stack buffer before giving random garbage to the SCU Fix stack buffer size for IPC writev messages intel_scu_ipc: Use the new cpu identification function intel_scu_ipc: tidy up unused bits Remove indirect read write api support. intel_scu_ipc: Support Medfield processors intel_scu_ipc: detect CPU type automatically x86 plat: limit x86 platform driver menu to X86 acpi ec_sys: Be more cautious about ec write access acpi ec: Fix possible double io port registration hp-wmi: acpi_drivers.h is already included through acpi.h two lines below hp-wmi: Fix mixing up of and/or directive dell-laptop: make dell_laptop_i8042_filter() static asus-laptop: fix asus_input_init error path msi-wmi: make needlessly global symbols static ...
