One wouldn't expect a "match" function modify the string it searches
for, and indeed the only instance of the struct
acpi_scan_handler::match callback, acpi_pnp_match, can easily be
changed. While there, update its helper matching_id().
This is also preparation for constifying struct acpi_hardware_id::id.

The IPMI SI driver was using direct PNP, but that was not really
ideal because the IPMI device is a platform device. There was
some special handling in the acpi_pnp.c code for making this work,
but that was breaking ACPI handling for the IPMI SSIF driver.
So without this patch there were significant issues getting the
SSIF driver to work with ACPI.
So use a platform device for ACPI detection and remove the
entry from acpi_pnp.c.

Commit eec15edbb0 (ACPI / PNP: use device ID list for PNPACPI device
enumeration) changed the way how ACPI devices are enumerated and when
they are added to the PNP bus.
However, it broke the sound card support on (at least) a vintage
IBM ThinkPad 600E: with said commit applied, two of the necessary
"CSC01xx" devices are not added to the PNP bus and hence can not be
found during the initialization of the "snd-cs4236" module. As a
consequence, loading "snd-cs4236" causes null pointer exceptions.
The attached patch fixes the problem end re-enables sound on the
IBM ThinkPad 600E.

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).

ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't
belong to PNP bus in nature.

Fujitsu backlight and hotkey devices have ACPI drivers.
The PNP MODULE_DEVICE_TABLE in fujitsu-laptop driver is just used as an
indicator for module autoloading, but this is wrong because what we
need is ACPI module device table instead, because the driver is probing
ACPI devices.
Thus remove those IDs from ACPI PNP scan handler list as we don't
have a PNP driver for them, and convert the fujitsu-laptop PNP
MODULE_DEVICE_TABLE to ACPI MODULE_DEVICE_TABLE.

The soc_button_array PNP driver was introduced in 3.15.
But in commit eec15edbb0 (ACPI / PNP: use device ID list for
PNPACPI device enumeration), when reworking the PNPACPI device
enumeration, we missed the soc_button_array device ID.
This results in a regression in 3.16-rc1 that soc_button_array
pnp device fails to be enumerated.
Fix the problem by adding soc_button_array device ID into the
acpi_pnp scan handler's ID list.

The "serial" PNP driver supports some "unknown" PNP modems
(PNPCXXX/PNPDXXX) by matching magic strings in the PNP device name
or the PNP device card name.
ACPI enumerated PNP devices neither are PNP cards, nor have those
magic strings in device names, so this mechamism never actually works
for ACPI enumerated PNPCXXX/PNPDXXX devices.
Consequently, it is safe to remove those two IDs from the PNP ACPI scan
handler's device ID list.

ACPI can be used to enumerate PNP devices, but the code does not
handle this in the right way currently. Namely, if an ACPI device
object
1. Has a _CRS method,
2. Has an identification of
"three capital characters followed by four hex digits",
3. Is not in the excluded IDs list,
it will be enumerated to PNP bus (that is, a PNP device object will
be create for it). This means that, actually, the PNP bus type is
used as the default bus type for enumerating _HID devices in ACPI.
However, more and more _HID devices need to be enumerated to the
platform bus instead (that is, platform device objects need to be
created for them). As a result, the device ID list in acpi_platform.c
is used to enforce creating platform device objects rather than PNP
device objects for matching devices. That list has been continuously
growing recently, unfortunately, and it is pretty much guaranteed to
grow even more in the future.
To address that problem it is better to enumerate _HID devices
as platform devices by default. To this end, change the way of
enumerating PNP devices by adding a PNP ACPI scan handler that
will use a device ID list to create PNP devices for the ACPI
device objects whose device IDs are present in that list.
The initial device ID list in the PNP ACPI scan handler contains
all of the pnp_device_id strings from all the existing PNP drivers,
so this change should be transparent to the PNP core and all of the
PNP drivers. Still, in the future it should be possible to reduce
its size by converting PNP drivers that need not be PNP for any
technical reasons into platform drivers.
