Input: serio/gameport - use 'long' system workqueue
Commit
8ee294cd9def0004887da7f44b80563493b0a097 converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().
To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.

Input: serio - clear pending rescans after sysfs driver rebind
When rebinding a serio driver via sysfs drvctl interface it is
possible for an interrupt to trigger after the disconnect of the
existing driver and before the binding of the new driver. This will
cause the serio interrupt handler to queue a rescan event which will
disconnect the new driver immediately after it is attached.
This change removes pending rescans from the serio event queue after
processing the drvctl request but before releasing the serio mutex.
Reproduction involves issuing a rebind of device port from psmouse
driver to serio_raw driver while generating input to trigger
interrupts. Then checking to see if the corresponding
i8042/serio4/driver is correctly attached to the serio_raw driver
instead of psmouse.

This is under the assumption that pen and touch share the same physical

Input: synaptics - ignore bogus mt packet
In multitouch mode, at least one device (fw: 7.4 id: 0x1c0b1) sometimes
sends a final main packet with x == 1. Since the normal values are above
1472, this is clearly bogus. At the same time, a two-finger touch is
signaled, even though only one finger was on the pad to begin with. This
patch ignores the packet altogether, removing the problem.

Input: synaptics - add multi-finger and semi-mt support
The Synaptics 2.7 series of touchpads support a mode for reporting two
sets of X/Y/Pressure data (advanced gesture mode). By default, these
devices report only single finger data, depriving userspace of the
nowadays ubiquitous two-finger scroll gesture.
Enabling advanced gesture mode also enables the multi-finger report,
although the device does not claim that capability. Up to three
fingers can be reported this way.
While two or three fingers are touching, the normal packet is
prepended by a reduced finger packet of lower resolution. From the two
packets (which do not represent the actual fingers), the bounding
rectangle of the individual contacts can be extracted. This
information is sufficient to perform scaling gestures and a limited
form of rotation gesture. The behavior has been coined semi-mt
capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT
device property.
Work to decode the advanced gesture packet: Takashi Iwai.

Minor cleanup and testing: Chris Bagwell.

Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while
extending them to support large scancodes was a mistake. While we tried
to keep ABI intact (and we succeeded in doing that, programs compiled
on older kernels will work on newer ones) there is still a problem with
recompiling existing software with newer kernel headers.
New kernel headers will supply updated ioctl numbers and kernel will
expect that userspace will use struct input_keymap_entry to set and
retrieve keymap data. But since the names of ioctls are still the same
userspace will happily compile even if not adjusted to make use of the
new structure and will start miraculously fail in the field.
To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions
and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly
select the style of ioctls it wants to employ.

Input: serio - convert to common workqueue instead of a thread
Instead of creating an exclusive thread to handle serio events (which
happen rarely), let's switch to using common workqueue. With the arrival
of concurrency-managed workqueue infrastructure we are not concerned
that our callers or callees also using workqueue (no deadlocks anymore)
and it should reduce total number of threads in the system.

Input: qt602240_ts - fix wrong sizeof in object table allocation
The kcalloc call for the object table is using sizeof(struct qt602240_data)
when it should be using sizeof(struct qt6602240_object), resulting in a larger
allocation than is required.

Input: xpad - ensure xpad->bulk_out is initialized before submitting urb
As pointed out by Oliver Neukum:
xpad->irq_in is currently submitted before xpad->bulk_out is allocated.
That however is a race, because the callback for irq_in can call
xpad360w_process_packet(), which will in turn submit the bulk URB.
This patch moves initialization for xpad->bulk_out earlier, so we can
ensure xpad->bulk_out is initialized before submitting urb.
