HID: multitouch: prevent memleak with the allocated name

2013-06-12T09:13:38+00:00

mt_free_input_name() was never called during .remove():
hid_hw_stop() removes the hid_input items in hdev->inputs, and so the
list is therefore empty after the call. In the end, we never free the
special names that has been allocated during .probe().

Restore the original name before freeing it to avoid acessing already
freed pointer.

This fixes a regression introduced by 49a5a827a ("HID: multitouch: append " Pen" to
the name of the stylus input")

HID: multitouch: fix touchpad buttons

2013-03-27T13:09:40+00:00

Commit "HID: multitouch: use the callback "report" instead..." breaks the
buttons of touchpads following the HID multitouch specification.
The buttons were emmitted through hid-input, but as now the events
are generated only in hid-multitouch, the buttons are not emmitted anymore.

The input_event() call is far much simpler than the hid-input one as
many of the different tests do not apply to multitouch touchpads.

The "tablet" udev rule relies on BTN_STYLUS to be set.

HID: multitouch: append " Pen" to the name of the stylus input

This is not just cosmetics, it can help to write udev and X.org
rules.

HID: multitouch: add handling for pen in dual-sensors device

2013-03-27T13:02:46+00:00

Dual sensors devices reports pen and touch on two different reports.
Using the quirk HID_QUIRK_MULTI_INPUT allows us to create a new input
device to forward pen events.

The quirk HID_QUIRK_NO_EMPTY_INPUT avoids the creation of input devices
for the not used mouse emulation present on Win7 certified devices.

Since hid-multitouch sets the quirk HID_QUIRK_NO_INPUT_SYNC, we need
to manually send SYN events for pen report too.

HID: multitouch: change touch sensor detection in mt_input_configured()

2013-03-27T13:02:46+00:00

To implement different methods for pen and touch, the previous
implementation has to be reworked.

This detection of the input attached to the touch sensor is the same
than the one used in mt_report().

HID: multitouch: do not map usage from non used reports

2013-03-27T13:02:46+00:00

hid-multitouch only handles touch events, so there is no point in
mapping other kind of events.

HID: multitouch: breaks out touch handling in specific functions

2013-03-27T13:02:45+00:00

This will allow easier integration of hybrid pen and touch devices.
