This reverts commits 61e00655e9cb, 73f8645db191 and 8e22ecb603c8:
"Input: introduce BTN/ABS bits for drums and guitars"
"HID: wiimote: add support for Guitar-Hero drums"
"HID: wiimote: add support for Guitar-Hero guitars"
The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic. It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.
We'll try again for 3.13.

Guitar-Hero comes with a drums extension. Use the newly introduced input
drums-bits to report this back to user-space. This is a usual extension
like any other device. Nothing special to take care of.
We report this to user-space as "Nintendo Wii Remote Drums". There are
other drums (like "RockBand" drums) which we currently do not support and
maybe will at some point. However, it is quite likely that we can report
these via the same interface. This allows user-space to work with them
without knowing the exact branding.
I couldn't find anyone who owns a "RockBand" device, though.

Some multitouch screens do not like to be polled for input reports.
However, the Win8 spec says that all touches should be sent during
each report, making the initialization of reports unnecessary.
The Win7 spec is less precise, so do not use this for those devices.
Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to
introduce a quirk for each problematic device. This quirk makes the driver
behave the same way the Win 8 does. It actually retrieves the features,
but not the inputs.

Detecting Win 8 multitouch devices in core allows us to set quirks
before the device is parsed through hid_hw_start().
It also simplifies the detection of those devices in hid-multitouch and
makes the handling of those devices cleaner.
As Win 8 multitouch panels are in the group multitouch and rely on a
special feature to be detected, this patch adds a bitfield in the parser.

The Win 8 detection is sufficiently complex to warrant use of the full
parser code, in spite of the inferred memory usage. Therefore, we can use
the existing HID parser in hid-core for hid_scan_report() by re-using the
code from hid_open_report(). hid_parser_global, hid_parser_local and
hid_parser_reserved does not have any side effects. We just need to
reimplement the MAIN_ITEM callback to have a proper parsing without side
effects.

traverse each hidraw_list node without a lock protection, the list
could be modified if someone calls hidraw_release and list_del to
remove itself from the list, this can cause hidraw_report_event

This reverts commit 407a2c2a4d85100c8c67953e4bac2f4a6c942335.
Explanation provided by Benjamin Tissoires:
Commit "HID: hid-logitech-dj, querying_devices was never set" activate
a flag which guarantees that we do not ask the receiver for too many
enumeration. When the flag is set, each following enumeration call is
discarded (the usb request is not forwarded to the receiver). The flag
is then released when the driver receive a pairing information event,
which normally follows the enumeration request.
However, the USB3 bug makes the driver think the enumeration request
has been forwarded to the receiver. However, it is actually not the
case because the USB stack returns -EPIPE. So, when a new unknown
device appears, the workaround consisting in asking for a new
enumeration is not working anymore: this new enumeration is discarded
because of the flag, which is never reset.
A solution could be to trigger a timeout before releasing it, but for
now, let's just revert the patch.

This changes puts the commit 4fe9f8e203f back in place
with the fixes for slab corruption because of the commit.
When a device is unplugged, wait for all processes that
have opened the device to close before deallocating the device.
This commit was solving kernel crash because of the corruption in
rb tree of vmalloc. The rootcause was the device data pointer was
geting excessed after the memory associated with hidraw was freed.
The commit 4fe9f8e203f was buggy as it was also freeing the hidraw
first and then calling delete operation on the list associated with
that hidraw leading to slab corruption.

GEN10 and earlier devices seem to not support DRM_KAI if we run in basic
IR mode. Use DRM_KAIE instead. This might increases overhead slightly as
the extension port is read and streamed but we stream accelerometer data
constantly, too, so this is negligible.
Note that our parsers are hardcoded on IR-formats, so we cannot actually
use 96-bit IR DRMs for basic IR data. We would have to adjust the parsers.
But as only GEN20 and newer support this, we simply avoid mixed DRMs.
This fixes a bug where GEN10 devices didn't provide IR data if
accelerometer and IR are enabled simultaneously. As a workaround, you can
enable DRM_KAIE without this patch via (disables device power-management):
