This avoids the problematic case:
if (condition)
i2c_hid_dbg(ihid, "Blah blah %d\n", i);
else
do_something_very_important();
Which looks correct, however with the previous macro definition,
this expands to the unexpected:
if (condition) {
if (debug) \
dev_printk(KERN_DEBUG, &ihid->client->dev,
"Blah blah %d\n", i);
else
do_something_very_important();
}

Microsoft published the protocol specification of HID over i2c:
http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx
This patch introduces an implementation of this protocol.
This implementation does not includes the ACPI part of the specification.
This will come when ACPI 5.0 devices enumeration will be available.
Once the ACPI part is done, OEM will not have to declare HID over I2C
devices in their platform specific driver.

In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed
support for MS 3k keyboards. However the added check using memcmp and
a compound statement breaks build on architectures where memcmp is a
macro with parameters.
hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3
On x86_64, memcmp is a function, so I did not see the error.

HID: hidraw: put old deallocation mechanism in place
This basically reverts commit 4fe9f8e203. It causes multiple problems,
namely:
- after rmmod/modprobe cycle of bus driver, the input is not claimed any
more. This is likely because of misplaced hid_hw_close()
- it causes memory corruption on hidraw_list
As original patch author is not responding to requests to fix his patch,
and the original deallocation mechanism is not exposing any problems, I
am reverting back to it.

Microsoft Digital Media Keyboard 3000 has two interfaces, and the
second one has a report descriptor with a bug. The second collection
says:
05 01 -- global; usage page -- 01 -- Generic Desktop Controls
09 80 -- local; usage -- 80 -- System Control
a1 01 -- main; collection -- 01 -- application
85 03 -- global; report ID -- 03
19 00 -- local; Usage Minimum -- 00
29 ff -- local; Usage Maximum -- ff
15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff
81 00 -- main; input
c0 -- main; End Collection
I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

"Here is the big staging tree update for the 3.7-rc1 merge window.
There are a few patches in here that are outside of the staging area,
namely HID and IIO patches, but all of them have been acked by the
relevant subsystem maintainers. The IIO stuff is still coming in
through this tree as it hasn't entirely moved out of the staging tree,
but is almost there.
Other than that, there wa a ton of work on the comedi drivers to make
them more readable and the correct style. Doing that removed a lot of
code, but we added a new driver to the staging tree, so we didn't end
up with a net reduction this time around:

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.
