This is a common pattern in the HID drivers to reset the drvdata. Some
do it properly, some do it only in case of failure.
But, this is actually already handled by driver core, so there is no need
to do it manually.

The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a
scrolling wheel capable of 2-D (vertical+horizontal) scrolling. hid-generic
does only expose 1-D (vertical) scrolling functionality for these mice. This
patch adds support for horizontal scrolling for the IBM/Lenovo Scrollpoint mice
to hid-lenovo.

The lenovo_send_cmd_cptkbd function uses a stack variable to submit
commands via hid_hw_raw_request. Eventually this gets to the
usb_hcd_map_urb_for_dma function, which causes a warning to be thrown
if the CONFIG_DMA_API_DEBUG option is enabled.
Fix this by allocating a temporary buffer instead.

When configuring input device via input_configured callback we may

Don't relay a middle button press to userspace until release, and then
only if there was no scroll events inbetween. This is closer to what
Xorg's wheel emulation does, and avoids spurious middle-click pastes.

By default the middle button is in a compatibility mode, and generates
standard wheel events when dragging with the middle trackpoint button.
Unfortunately this is buggy:
* The middle button comes up before starting wheel events, causing a middle
click on whatever the mouse cursor was sitting on
* The USB keyboard always generates the "native" horizontal wheel event,
regardless of mode.
Instead, enable the "native" mode the Windows driver uses, and add support
for the custom events this generates. This fixes the USB keyboard wheel
events, and the middle-click up event comes after the wheel events.
