When reviewing another thingm patch Benjamin Tissoires pointed out
the following: "The problem here is that hid_hw_start() is called
before thingm_version() which allows user space to briefly introduce
races between thingm_version() and any hidraw requests.
The mutex will not help here as it is initialized after hid_hw_start()
and only used for protecting the concurrent access of the rgb."
Avoid this possible issue by calling hid_hw_start() later in the
probe function.

Even though hid_hw_* checks that passed in data_len is less than
HID_MAX_BUFFER_SIZE it is not enough, as i2c-hid does not necessarily
allocate buffers of HID_MAX_BUFFER_SIZE but rather checks all device
reports and select largest size. In-kernel users normally just send as much
data as report needs, so there is no problem, but hidraw users can do

On ACPI-based systems ACPI power domain code runtime resumes device before
calling suspend method, which ensures that i2c-hid suspend code starts with
device not in low-power state and with interrupts enabled.
On other systems, especially if device is not a part of any power domain,
we may end up calling driver's system-level suspend routine while the
device is runtime-suspended (with controller in presumably low power state
and interrupts disabled). This will result in interrupts being essentially
disabled twice, and we will only re-enable them after both system resume
and runtime resume methods complete. Unfortunately i2c_hid_resume() calls
i2c_hid_hwreset() and that only works properly if interrupts are enabled.
Also if device is runtime-suspended driver's suspend code may fail if it
tries to issue I/O requests.
Let's fix it by runtime-resuming the device if we need to run HID driver's
suspend code and also disabling interrupts only if device is not already
runtime-suspended. Also on resume we mark the device as running at full
power (since that is what resetting will do to it).

This patch implements force feedback support for the Logitech
G920 Driving Force Racing Wheel. It is a generic implementation
of feature 0x8123 of the Logitech HID++ protocol and should be
usable for any future devices that implement this feature.
This patch should be applied after the basic G920 support patch
by Simon Wood:
http://www.spinics.net/lists/linux-input/msg42174.html
The driving supports everything that is supported by the G920
firmware:
FF_CONSTANT
FF_PERIODIC
FF_SINE
FF_SQUARE
FF_SAW_UP
FF_SAW_DOWN
FF_TRIANGLE
FF_SPRING
FF_DAMPER
FF_AUTOCENTER
FF_GAIN
and for version 2 firmware also:
FF_FRICTION
FF_INERTIA
FF_RAMP
Both envelopes and replay values are supported as well, but some
problems may occur when using firmware release 1. There is also a
small residual clockwise damper in the wheel when using the first
firmware release. All problems are fixed in the soon te be released
firmware version 2.
The default spring is disabled by permanently placing a spring
force in the wheel. This spring is also used as the autocenter
spring.
Note: The wheel _DOES_NOT_ auto switch to Logitech/HID mode (it is stuck
in XBox since the xpad changes where not included). Michal has an
alternative approach documented here (and the changes should be submitted
upstream to usb_modeswitch project):
===
Create a file named "046d:c261" in "/etc/usb_modeswitch.d" with the
following content:
DefaultVendor=046d
DefaultProduct=c261
MessageEndpoint=01
ResponseEndpoint=01
TargetClass=0x03
MessageContent="0f00010142"
Then run "usb_modeswitch -c /etc/modeswitch.d/046d:c291" as root and
watch the magic happen:)

Commit 0925636042 ("HID: rmi: Disable scanning if the device is not a wake
source") introduced a regression for devices which use hid-rmi to handle
composite USB devices. The suspend or resume callbacks are not checking
that the device is a RMI device before calling rmi_read or rmi_write.
This results in dereferencing uninitialized variables on non RMI devices. This
patch checks that the RMI_DEVICE flag is set before sending RMI commands to the
device.

The weird part is that the initial commit that added this: a7de9b8

very same controller as one requiring this output report.
Anyway, it's broken for one user at least, so let's change it.
We will report an error, but at least the controller should work.
And no, these devices present themselves as legacy Sony controllers

Pull vfs fix from Al Viro:
"Don't put symlink bodies in pagecache into highmem"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
Make sure that highmem pages are not added to symlink page cache
inode_nohighmem() is sufficient to make sure that page_get_link()
won't try to allocate a highmem page. Moreover, it is sufficient
to make sure that page_symlink/__page_symlink won't do the same
thing. However, any filesystem that manually preseeds the symlink's
page cache upon symlink(2) needs to make sure that the page it
inserts there won't be a highmem one.
Fortunately, only nfs and shmem have run afoul of that...
