Certain versions of Cypress USB barcode readers (this problem is known to
happen at least with PIDs 0xde61 and 0xde64) have report descriptor which
has swapped usage min and usage max tag. This results in HID parser failing
for report descriptor of these devices, as it (wrongly) requires allocating
more usages than HID_MAX_USAGES.

Solve this by walking through the report descriptor for such devices, and swap
the usage min and usage max items (and their values) to be in proper order.

Some HID devices are looking on the unused bits in the HID reports they
receive. This is violating the specification, but we want to make those
devices work. Well-behaving devices are unaffected, as they don't care
about the unused bits.

If bitsused % 8 is 0 all bits in data[] get used and we don't need to
clear anything. Otherwise (bitsused % 8) bits of the last byte get used.
By shifting 1 for (bitsused % 8) bits and subtracting 1 we create a mask
consisting of (bitsused % 8) ones and remaining zeroes. By ANDing we
clear the upper unused bits.

The USB HID driver fails to reset its error-retry timeout when there
has been a long time interval between I/O errors with no successful URB
completions in the meantime.  As a result, the very next error would
trigger an immediate reset, even if it was a chance event occurring
long after the previous error.

More USB keyboards and mice than one might expect end up getting I/O
errors. Almost always this results from hardware problems of one sort of
another. For example, people attach the device to a USB extension cable,
which degrades the signal.  Or they simply have poor quality cables to
begin with. Or they use a KVM switch which doesn't handle USB messages
correctly. Etc...

There have been reports from several users in which these I/O
errors would occur more or less randomly, at intervals ranging from
seconds to minutes.  The error-handling code in hid-core.c was originally
meant for situations where a single outage would persist for a few hundred
ms (electromagnetic interference, for example).  It didn't work right when
these more sporadic errors occurred, because of a flaw in the logic
which this patch fixes.

This patch (as873) fixes that oversight.

This patch removes bogus zeroing of unused bits in output reports,
introduced in Simon's patch in commit d4ae650a.
According to the specification, any sane device should not care
about values of unused bits.

What is worse, the zeroing is done in a way which is broken and
might clear certain bits in output reports which are actually
_used_ - a device that has multiple fields with one value of
the size 1 bit each might serve as an example of why this is
bogus - the second call of hid_output_report() would clear the
first bit of report, which has already been set up previously.

This patch will break LEDs on SpaceNavigator, because this device
is broken and takes into account the bits which it shouldn't touch.
The quirk for this particular device will be provided in a separate
patch.

hid_parser is non-trivially large structure, so it should be allocated
using vmalloc() to avoid unsuccessful allocations when memory fragmentation
is too high.
This structue has a very short life, it's destroyed as soon as the report
descriptor has been completely parsed.

This should be considered a temporary solution, until the hid_parser is
rewritten to consume less memory during report descriptor parsing.

Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.

The commit 35068976 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.

To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we
disable remapping for key, abs and rel events only for this hardware.

maximum and the number of usages is bumped up to 0x104d). The values are in the

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
