+/*
+ * msi-laptop.c - MSI S270 laptop support. This laptop is sold under
+ * various brands, including "Cytron/TCM/Medion/Tchibo MD96100".
+ *
+ * Driver also supports S271, S420 models.
+ *
+ * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/:
+ *
+ * lcd_level - Screen brightness: contains a single integer in the
+ * range 0..8. (rw)
+ *
+ * auto_brightness - Enable automatic brightness control: contains
+ * either 0 or 1. If set to 1 the hardware adjusts the screen
+ * brightness automatically when the power cord is
+ * plugged/unplugged. (rw)
+ *
+ * wlan - WLAN subsystem enabled: contains either 0 or 1. (ro)
+ *
+ * bluetooth - Bluetooth subsystem enabled: contains either 0 or 1
+ * Please note that this file is constantly 0 if no Bluetooth
+ * hardware is available. (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/msi-laptop-bl/.
+ *
+ * This driver might work on other laptops produced by MSI. If you
+ * want to try it you can pass force=1 as argument to the module which
+ * will force it to load even when the DMI data doesn't identify the
+ * laptop as MSI S270. YMMV.
