This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.

This driver exports a few files in /sys/devices/platform/compal-laptop/:
 lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
 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/.

Sys I/F under acpi device node and sysdev device node are both
needed for cpu hot-removal. User space need this link so that
they know they are poking the sys I/F for the same cpu.

The ACPI device node for the cpu has already been unregistered
when acpi_processor_handle_eject is called.
Thus we should offline the cpu and continue, rather than a failure here.

"/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method
and eject a device in user space.
But system hangs when poking the "eject" file because that
the device hot-removal code invoke the driver .remove method which will
try to remove the "eject" file as a result.

Queues the hot-removal function for deferred execution in this patch.

The ad7418 driver is only used on embedded platforms where i2c
devices can easily be declared in platform code. Thus a new-style
i2c driver makes perfect sense. This lets us get rid of quirky
detection code (these chips have no identification registers) and
shrinks the binary driver size by 38%.
