create drivers/platform/x86/ from drivers/misc/
Move x86 platform specific drivers from drivers/misc/ to a new home under drivers/platform/x86/. The community has been maintaining x86 vendor-specific platform specific drivers under /drivers/misc/ for a few years. The oldest ones started life under drivers/acpi. They moved out of drivers/acpi/ because they don't actually implement the ACPI specification, but either simply use ACPI, or implement vendor-specific ACPI extensions. In the future we anticipate... drivers/misc/ will go away. other architectures will create drivers/platform/<arch> Signed-off-by: Len Brown <len.brown@intel.com>

-/*
- * fujitsu-laptop.c - Fujitsu laptop support, providing access to additional
- * features made available on a range of Fujitsu laptops including the
- * P2xxx/P5xxx/S6xxx/S7xxx series.
- *
- * This driver exports a few files in /sys/devices/platform/fujitsu-laptop/;
- * others may be added at a later date.
- *
- * lcd_level - Screen brightness: contains a single integer in the
- * range 0..7. (rw)
- *
- * In addition to these platform device attributes the driver
- * registers itself in the Linux backlight control subsystem and is
- * available to userspace under /sys/class/backlight/fujitsu-laptop/.
- *
- * Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are
- * also supported by this driver.
- *
- * This driver has been tested on a Fujitsu Lifebook S6410, S7020 and
- * P8010. It should work on most P-series and S-series Lifebooks, but
- * YMMV.
- *
- * The module parameter use_alt_lcd_levels switches between different ACPI
- * brightness controls which are used by different Fujitsu laptops. In most
- * cases the correct method is automatically detected. "use_alt_lcd_levels=1"
- * is applicable for a Fujitsu Lifebook S6410 if autodetection fails.
