* 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 implements a vendor-specific backlight control interface for
+ * Fujitsu laptops and provides support for hotkeys present on certain Fujitsu
+ * laptops.
*
* 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
