Sysfs attributes affecting device behavior should not be, by default,
world-writeable. If distributions want to allow console users access
these attributes they need to employ udev and friends to adjust
permissions as needed.

Cintiq, being a display tablet, doesn't have mouse and associated BTN_s.
Make sure we do not specify them when registering Cintiq's input device
so that userland can retrieve the exact tool set the device supports.

We need to always call usb_autopm_put_interface() in wacom_open(),
not only when initialization fails, otherwise the device will be
marked as PM-busy and will never be put in suspended state.

When runtime PM is enabled by default for input devices, X hangs in
wacom open:
[<ffffffff814a00ea>] mutex_lock+0x1a/0x40
[<ffffffffa02bc94b>] wacom_resume+0x3b/0x90 [wacom]
[<ffffffff81327a32>] usb_resume_interface+0xd2/0x190
[<ffffffff81327b5d>] usb_resume_both+0x6d/0x110
[<ffffffff81327c24>] usb_runtime_resume+0x24/0x40
[<ffffffff8130a2cf>] __pm_runtime_resume+0x26f/0x450
[<ffffffff8130a23a>] __pm_runtime_resume+0x1da/0x450
[<ffffffff8130a53a>] pm_runtime_resume+0x2a/0x50
[<ffffffff81328176>] usb_autopm_get_interface+0x26/0x60
[<ffffffffa02bc626>] wacom_open+0x36/0x90 [wacom]
wacom_open() takes wacom->lock and calls usb_autopm_get_interface(),
which in turn calls wacom_resume() which tries to acquire the lock
again.
The fix is to call usb_autopm_get_interface() first, before we take
the lock.
Since we do not do usb_autopm_put_interface() until wacom_close()
is called runtime PM is effectively disabled for the driver, however
changing it now would risk regressions so the complete fix will
have to wait till the next merge window.

Bamboo P&T need to use second form of usb_set_report() to
ask to report tablet data.
With previous addition of Bamboo Touch, BTN_TOOL_TRIPLETAP is now used
for both TABLETPC2FG and BAMBOO_PT types. So reduced check to
match type=TABLETPC2FG.
This change shows redundant check for !TABLETPC2FG in else statement.

The Bamboo Touch reports a sub-screen resolution of 480x320. The
signal-to-noise ratio is only about 100, so filtering is needed in
order to reduce the jitter to a usable level. However, the low
resolution leads to round-off errors in the EWMA filter, resulting in
extremely jerky pointer motion. This patch explicitly sets a higher
resolution for those devices, and tells this to the completion handler
via a low-resolution quirk.

This fixes a regression introduced in
3b57ca0f80c5c8994b5b1e3d3f904cfe727951f2.
The data[6] byte contains either 1 or -1 depending on the whether the
mouse wheel on older wacom tablets is moved down (1) or up (-1). The
patch introduced in the above commit changed the cast from (signed char)
to (signed). When cast as a signed integer and negated, the value of -1
(stored in the byte as 0xff) became -255 rather than 1. This patch
reverts the cast to a (signed char) and also removes an unnecessary
(signed) cast, as all the values operated on are bitmasked.

usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()
They should only be used in code which really needs DMA coherency.

Touch enbaled devices share the same product ID with pen. However,
we do not want to post touch events while pen is in prox. To do so,
we used to keep a local static variable to keep track of if pen is
in prox or not. This works fine for Tablet PC devices since there
is only one device attached. With the newer touch enabled regular
tablets, we can not make this assumption any more, i.e, one system
may have more than one identical tablet plugged in.
This patch adds an new entry, shared, into the struct wacom_wac so
touch data can access pen data to locally. This solution assumes
the two tools (touch and pen) of the same ID will be probed one
after the other without interruption in between by another Wacom
device of the same ID.
