Use the `PLATFORM_DEVID_NONE` constant instead of hard-coding -1 when creating a platform device. No functional changes are intended.

/*
|
|
* 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.
