In preparation for struct class_device -> struct device input
core conversion switch to using input_dev->dev.parent when
specifying device position in sysfs tree.

usb_buffer_free() now handles NULLs so remove unneeded checks
form callers.

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.

Move the USB_VENDOR* and USB_DEVICE* defines and the hid_blacklist[]
array there from hid-core.c. Add
hid-quirks.c:usbhid_lookup_any_quirks() to return quirk information to
hid-core.c. Convert __u32, __u16 types to u32, u16.

Add HID_QUIRK_MULTI_INPUT to the EMS USBII (0x0b43/0003) so the kernel detects both joystick
ports properly. Without it you end up with a single joystick node (js0) that combines the
two physical port signals.

This adds support for WiseGroup Quad Joypad (0x0925/0x8800). The
same quirks as for Dual Joypad (0x0925/0x8866) are needed.

On Dell W7658 keyboard, when BIOS sets NumLock LED on, it survives the
takeover by kernel and thus confuses users.
Eating of an increasibly scarce quirk bit is unfortunate. We do it for safety,
given the history of nervous input devices which crash if anything unusual
happens.

Logitech MX3000 contains report descriptor which doesn't cover usages
above 0x28c, but emits such usages. Report descriptor needs fixing
in the very same way as with receivers shipped with S510 keyboards.
This patch also adds a few mappings for multimedia keys that S510 didn't
emit.

Logitech S510 keyboard is shipped with USB receivers with various product
ids, all need their report descriptor to be fixed. This adds PID 0xc50c.

Add HID_QUIRK_HIDDEV for the Belkin Flip USB KVM, which provides for software
control of switching via a HID class interface. It overloads three HID LED
usages, two of which aren't mapped in the ev_dev input subsection, and which it
doesn't make sense to map. In order to force the creation of a hiddev device
for controlling the Flip, this quirk flag is needed.

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.

The vendor/product IDs for the purposes of hid_blacklist got
scathered around the hid-core.c in a rather random way over the
time.
Move all the related definitions at the beginning of the file,
and make them sorted again. Sort also hid_blacklist properly.
