d47bb5b227 asus_acpi: fix a memory leak in asus_hotk_get_info()
In the case of no match ( hotk->model == END_MODEL ), model sholud be
kfreed before return AE_OK.

This patch includes below fixes:

1. adds a missing kfree(model) before return AE_OK.

2. asus_hotk_get_info should return int, thus return 0 instead of AE_OK.

80183a4b63 compal-laptop/fujitsu-laptop/msi-laptop: make dmi_check_cb to return 1 instead of 0
dmi_check_system() walks the table running matching functions until
someone returns non zero or we hit the end.

This patch makes dmi_check_cb to return 1 so dmi_check_system() return

9be0fcb5ed compal-laptop: add JHL90, battery & hwmon interface
The driver now supports the Compal JHL90 (which I use) and it has some
added features.  The biggest novelties are a battery interface
(power_supply) and a temperature and fan control interface (hmwon).  It
also adds a power-off feature to the backlight subsystem and it exports a
few files that can enable/disable wake_on_XXX events.

Much of the original code of the old features is still there, but I've
changed some names to keep the naming more coherent with the added
functionalities.  (Sorry for the huge patch)

Some technical stuff about the new driver:

First of all, I'm not sure if the extra features also work on the other
Compal boards.  Currently they only get enabled if the DMI data indicates
you are on a JHL90 board.

Secondly, I've noticed a quirk in my fan controller.  I have to re-send
the wanted pwm-level to the controller every so often.  If I don't do
this, the fanspeed will slowly rise until after a couple of minutes it's
at full speed.  (Note that every normal userland application will probably
update the pwm-level every so often anyway, based on temperature readings,
so this might not be an issue in practice) If this turns out to be a
problem with all the controllers, maybe we should implement a kernel timer
and have the driver re-send the pwm level every XX seconds to make this
transparent to userspace?  (However, I couldn't immediately find a way to
do this cleanly.)

Additional information can be found in the source comments.

check their value too and bail out appropriately if the allocation

While at it, add one more kfree to the fail path. It is not necessary

And for completeness.

aa7ffc01d2 x86 platform driver: intelligent power sharing driver
Intel Core i3/5 platforms with integrated graphics support both CPU and
GPU turbo mode.  CPU turbo mode is opportunistic: the CPU will use any
available power to increase core frequencies if thermal headroom is
available.  The GPU side is more manual however; the graphics driver
must monitor GPU power and temperature and coordinate with a core
thermal driver to take advantage of available thermal and power headroom
in the package.

The intelligent power sharing (IPS) driver is intended to coordinate
this activity by monitoring MCP (multi-chip package) temperature and
power, allowing the CPU and/or GPU to increase their power consumption,
and thus performance, when possible.  The goal is to maximize
performance within a given platform's TDP (thermal design point).

- Improve error handling, by explictly return zero for success, error otherwise
- WMI query command can have arbitrary input sized params
- WMI query command can have specific output sized params (0, 4, 128,..) byte

I like to go on here, but this is a rather intrusive change that should
be looked at first. I am sure the one or other thing can be done better or
there might be typo/bug somewhere.

This did not get any testing yet, only compile tested.

Next steps could be:
  - Eventually introduce hp_wmi_perform_{read,write}_query macros
  - Introduce new wireless query interface (0x1B)
  - more

8dda6b0410 x86 platform drivers: hp-wmi fix buffer size depending on ACPI version
Depending on ACPI version (1.0 -> 32 bit) an integer could be
32 or 64 bit long. _WED internal concatenates two integers and
the return value will be 8 byte (2* 32 bit) or 16 byte (2* 64 bit)
long, depending on the ACPI version.

Also the data send with the WMI event is defined to be splitted into:
  - Event ID -> 4 bytes
  - Event Data -> 4 bytes

This gets messed up with new ACPI versions.
But it's a HP BIOS bug that may get fixed in the future
-> Support both, 16 and 8 byte _WED buffers.

Also the wrong assumption that from the event data sent, only the
first byte is relevant got cleaned up that it fits event_id/event_data
as described above.

fc3155b2c6 X86 platform wmi: Introduce debug param to log all WMI events
To give people easily an idea what could be WMI driven on their system.
Introduces:
wmi.debug=[01]

Tested on an acer:
ACPI: WMI: DEBUG Event INTEGER_TYPE - 65535

Situation where a driver registers for specific event and debug
handler gets overridden and set again if the registering driver gets
unloaded again is untested, but should work.
