/*
* comapl-laptop.c - Compal laptop support.
*
- * This driver exports a few files in /sys/devices/platform/compal-laptop/:
- *
- * wlan - wlan subsystem state: contains 0 or 1 (rw)
- *
- * bluetooth - Bluetooth subsystem state: contains 0 or 1 (rw)
- *
- * raw - raw value taken from embedded controller register (ro)
- *
- * 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/compal-laptop/.
+ * The driver registers itself with the rfkill subsystem and
+ * the Linux backlight control subsystem.
*
* This driver might work on other laptops produced by Compal. If you
* want to try it you can pass force=1 as argument to the module which
