Input: wacom - switch mode upon system resume

2010-04-15T18:16:10+00:00

When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.

wacom_retrieve_hid_descriptor is removed from wacom_resume due
to the fact that the required descriptors are stored properly
upon system resume.

Input: wacom - add device type to device name string

2010-02-20T09:22:44+00:00

Devices supporting both pen and touch features share the same product ID,
but presented as 2 separate input devices. By adding device type to device
name string we can help userspace applications and users differentiate
between them. 'Finger' is used for the touch since touch has been used as
a suffix by userland hotplugging services.

Input: wacom - use per-device instance of wacom_features

2010-02-19T09:25:16+00:00

Since we mangle data in wacom_features when dealing with certain devices let's
use a private (per-device) instance of wacom_features in wacom_wac. This way
same product ID can support more than one type of device, such as pen and touch,
and not interfere with each other.

tablets and two finger touch devices.

This patch fixed a bug that was introduced in kernel 2.6.28 for
TabletPC touch data. The wacom_parse_hid routine in wacom_sys.c
should always return 0 even when usb_control_msg got an error.
