The Sony PS3 Blue-ray Disc Remote Control used to be supported by the
BlueZ project's user space, but the code that handled it was recently
removed as its functionality conflicted with a real HSP implementation
and the mapping was thought to be better handled in the kernel. This is
a port of the mapping logic from the fakehid driver by Marcel Holtmann
to the in-kernel HID layer.
We also add support for the Logitech Harmony Adapter for PS3, which
emulates the BD Remote.

The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.
usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

The lg4ff driver doesn't fill the "input_absinfo" struct so it is left
with default values. Applications with rely on information in this struct
therefore do not work correctly with the wheel.
Other Logitech wheels probably need this fix too, but again I do not have
enough information to write it.

Range limiting command for the Driving Force Pro wheel is only a FF_SPRING
effect so that the wheel creates resistance when the user tries to turn it past
the limit. It is however possible to overpower the FFB motors quite easily which
leads to the X axis value exceeding the expected limit. This confuses
games which dynamically adjust calibration using the highest/lowest min and max
values reported by the wheel. Joydev device driver also doesn't take in account
any changes in an axis range after the joystick device is created.
This patch recalculates received ABS_X axis value so it is always in
<0; 16383> range where 0 is the left limit and 16383 the right limit.
Logitech driver for Windows does the same thing. As for any concerns about
possible loss of precision, I compared a large set of raw/adjusted values
generated by "mult_frac" to values returned by the Windows driver and I got
a 100% match.
Other Logitech wheels will probably need a similar fix, but I currently lack
the information needed to write one.

Make sure we keep enough space for terminating NUL character after last
newline. If we have too much data, replace last byte with '.'s to
make overflow visible.
Using hex_dump_to_buffer() is not interesting as it adds more overhead
and does not append the trailing linefeed.

This patch fixes an issue introduced after commit 4ea5454203d991ec
("HID: Fix race condition between driver core and ll-driver").
After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.
This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.
This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.
Based on a patch originally written by Benjamin Tissoires.

Pull Input and HID updates for 3.7 from Henrik Rydberg:
"The tree contains input core changes, Acked by Dmitry, which substantially
reduces the irqsoff latency for all input devices. It also contains MT changes
which allows further memory reduction, speedup and hardware support in the HID
Multitouch driver. Lastly, you get the conversion of the bcm5974 driver to
MT-B, which due to the mixed dependency of the tree fits better here than
anywhere else."

to prepare or finalize the configuration per input device. Currently,
there is no sane way for a driver to know when a device has been

Commit 4ea5454203d991ec85264f64f89ca8855fce69b0
[HID: Fix race condition between driver core and ll-driver] introduced
new locking around probe/remove functions that prevents any report/reply
from hardware to reach driver until it returned from probe.
As such, the ask-reply way to checking picoLCD firmware version during
probe is bound to timeout and let probe fail.
Drop the check to let driver successfully probe again (until locking issues
are resolved allowing to reinstate the check).

Access to struct picolcd_data is now protected with struct
