Input: wacom - fix pressure in Cintiq 21UX2

2010-10-10T21:16:09+00:00

Currently the pressure range in Cintiq 21UX2 is limited to half of the
supported. This patch fixes the problem.

Input: wacom - fix runtime PM related deadlock

2010-10-05T05:36:41+00:00

When runtime PM is enabled by default for input devices, X hangs in
wacom open:
[] mutex_lock+0x1a/0x40
[] wacom_resume+0x3b/0x90 [wacom]
[] usb_resume_interface+0xd2/0x190
[] usb_resume_both+0x6d/0x110
[] usb_runtime_resume+0x24/0x40
[] __pm_runtime_resume+0x26f/0x450
[] __pm_runtime_resume+0x1da/0x450
[] pm_runtime_resume+0x2a/0x50
[] usb_autopm_get_interface+0x26/0x60
[] 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.

Input: wacom - fix mousewheel handling for old wacom tablets

2010-08-29T04:39:04+00:00

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.

Input: switch to input_abs_*() access functions

2010-08-03T03:29:56+00:00

Change all call sites in drivers/input to not access the ABS axis
information directly anymore. Make them use the access helpers instead.

Also use input_set_abs_params() when possible.
Did some code refactoring as I was on it.

2010-06-22T18:32:24+00:00

Cintiq 21UX2 added 8 more bits for the tool serial number and more
buttons for the expresskey. We did not enable them properly in the
last patch.
