- * 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/.
- *
- * This driver has been tested on a Fujitsu Lifebook S7020.  It should
- * work on most P-series and S-series Lifebooks, but YMMV.
