Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86
Pull x86 platform driver updates from Matthew Garrett: "Some significant updates to samsung-laptop, additional hardware support for Toshibas, misc updates to various hardware and a new backlight driver for some Apple machines." Fix up trivial conflicts: geode Geos update happening next to net5501 support, and MSIC thermal platform support added twice. * 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86: (77 commits) acer-wmi: add quirk table for video backlight vendor mode drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() avoid NULL deref samsung-laptop: unregister ACPI video module for some well known laptops acer-wmi: No wifi rfkill on Sony machines thinkpad-acpi: recognize Lenovo as version string in newer V-series BIOS asus-wmi: don't update power and brightness when using scalar eeepc-wmi: split et2012 specific hacks eeepc-wmi: refine quirks handling asus-nb-wmi: set panel_power correctly asus-wmi: move WAPF variable into quirks_entry asus-wmi: store backlight power status for AIO machine asus-wmi: add scalar board brightness adj. support samsung-laptop: cleanup return type: mode_t vs umode_t drivers, samsung-laptop: fix usage of isalnum drivers, samsung-laptop: fix initialization of sabi_data in sabi_set_commandb asus-wmi: on/off bit is not set when reading the value eeepc-wmi: add extra keymaps for EP121 asus-nb-wmi: ignore useless keys acer-wmi: support Lenovo ideapad S205 Brazos wifi switch acer-wmi: fix out of input parameter size when set ...
