pc87360: Check for error on sysfs files creation
Use sysfs_create_group() for 2 sensor-types which are chip-model
invariant, i.e. all-or-nothing attribute groups.
Other 2 groups vary too much due to configuration, etc, so we keep the
loops of device_create_file(), but now check their returns.

pc87360: Delete sysfs files on device deletion
Add 4 explicit attribute groups for the 5 sensor types:
voltage (in), therm, temp, and fan & pwm (together in one group).
Use sysfs_remove_group() to drop them, but keeps the existing
startup code, which calls device_create_file in loops.

pc87360: Move some code around
Moves code for get-set-decl tuples for 3 items: cpu0_vid, vrm, alarms_in
up, to just after the get-set-decl tuple for voltages.
These items are already 'activated' together with the rest of the
voltage attributes, so the move tightens the grouping that's made
explicit in next patch.

hwmon: New driver for the VIA VT1211
This is a new driver for the VIA VT1211 Super-IO chip. It is a rewrite
of the existing vt1211 driver (by Mark D. Studebaker and Lars Ekman)
which has been around for a while but never made it into the main
kernel tree.
It is implemented as a platform driver and therefore requires
lm_sensors 2.10.1 to function properly.

w83791d: Documentation update
The alarm bits and the beep enable bits are in different positions in
the hardware. Document the problem and leave it to the user-space code
to handle the situation. When this driver is updated to the standardized
sysfs alarm/beep methodology, this won't be a problem.
This is a documentation only change.

This patch contains rudimentary suspend / resume support for the uguru,
this protects the uguru and the driver against suspend / resume cycles,
so there is no reason to unload the driver in your suspend / resume
scripts.
Only include suspend / resume functions when CONFIG_PM is set.

it87: Add support for the IT8718F
The IT8718F is a Super-I/O chip with integrated hardware monitoring
functions. It is very similar to the IT8716F, so adding support to the
it87 driver was pretty straightforward. The most significant difference
is that the IT8718F has up to 8 VID pins, instead of 6 for the older
chips.
For the IT8718F, the VID value can only be read from Super-I/O space.
Userspace support is already in lm_sensors SVN (to be soon released
as 2.10.1.)

Major cleanup of all s390 inline assemblies. They now have a common
coding style. Quite a few have been shortened, mainly by using register
asm variables. Use of the EX_TABLE macro helps as well. The atomic ops,
bit ops and locking inlines new use the Q-constraint if a newer gcc
is used. That results in slightly better code.
Thanks to Christian Borntraeger for proof reading the changes.

Adapted from an earlier patch by Greg KH <gregkh@suse.de>.
That patch added multiple read urbs and larger transfer buffers to allow
data transfers at full EvDO speed.
This version includes additional device IDs and fixes a memory leak in
the transfer buffer allocation.
Some (maybe all?) of the supported devices present multiple bulk endpoints,
the additional EPs can be used for control and status functions,
This version allocates 3 EPs by default, that can be changed using
the 'endpoints' module parameter.
Tested with Sierra Wireless EM5625 and MC5720 embedded modules.
Device ID (0x0c88, 0x17da) for the Kyocera Wireless KPC650/Passport
was added but is not yet tested.

This revamps handling of the hardware "async advance" IRQ, and its watchdog
timer. Basically it dis-entangles that important timeout from the others,
simplifying the associated state and code to make it more robust.
This reportedly improves behavior of EHCI on some systems with VIA chips,
and AFAIK won't affect non-VIA hardware. VIA systems need this code to
recover from silcon bugs whereby the "async advance" IRQ isn't issued.

before the system sleep then normally the PM core would not resume it
afterward. Without this resume, various sorts of wakeup events (like
port change events) can get lost.

When ohci-hcd is shutting down (for rmmod or PC-card removal), there is
a window when the device is shut down, HC communication area (->hcca)
is freed, but the core has not called "free_irq" yet. If another device
triggers a shared interrupt in this window, we oops when trying to
access the freed ->hcca.
This patch removes the window by calling free_irq before ->hcca is freed.
The patch is tested at the PC hotplug test rig at Stratus, and with
rmmod by Rafael Wysocki.

The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.
I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

This "u132-hcd" module is one half of the "driver" for
ELAN's U132 which is a USB to CardBus OHCI controller
adapter. This module needs the "ftdi-elan" module in
order to communicate to CardBus OHCI controller inserted
into the U132 adapter.
When the "ftdi-elan" module detects a supported CardBus
OHCI controller in the U132 adapter it loads this "u132-hcd"
module.
Upon a successful device probe() the single workqueue
is started up which does all the processing of commands
from the USB core that implement the host controller.
The workqueue maintains the urb queues and issues commands
via the functions exported by the "ftdi-elan" module. Each
such command will result in a callback.
Note that the "ftdi-elan" module is a USB client driver.
Note that this "u132-hcd" module is a (cut-down OHCI)
host controller.
Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

This "ftdi-elan" module is one half of the "driver" for
ELAN's Uxxx series adapters which are USB to PCMCIA CardBus
adapters. Currently only the U132 adapter is available and
it's module is called "u132-hcd".
When the USB hot plug subsystem detects a Uxxx series adapter
it should load this module.
Upon a successful device probe() the jtag device file interface
is created and the status workqueue started up.
The jtag device file interface exists for the purpose of
updating the firmware in the Uxxx series adapter, but as
yet it had never been used.
The status workqueue initializes the Uxxx and then sits there
polling the Uxxx until a supported PCMCIA CardBus device is
detected it will start the command and respond workqueues
and then load the module that handles the device. This will
initially be only the u132-hcd module. The status workqueue
then just polls the Uxxx looking for card ejects.
The command and respond workqueues implement a command
sequencer for communicating with the firmware on the other
side of the FTDI chip in the Uxxx. This "ftdi-elan" module
exports some functions to interface with the sequencer.
Note that this module is a USB client driver.
Note that the "u132-hcd" module is a (cut-down OHCI)
host controller.
Thus we have a topology with the parent of a host controller
