HID: add mapping for KEY_DICTATE

2022-03-08T18:07:50+00:00

commit bfa26ba343c727e055223be04e08f2ebdd43c293 upstream.

Numerous keyboards are adding dictate keys which allows for text
messages to be dictated by a microphone.

This patch adds a new key definition KEY_DICTATE and maps 0x0c/0x0d8
usage code to this new keycode. Additionally hid-debug is adjusted to
recognize this new usage code as well.

HID:Add support for UGTABLET WP5540

commit fd5dd6acd8f823ea804f76d3af64fa1be9d5fb78 upstream.

This patch adds support for the UGTABLET WP5540 digitizer tablet
devices. Without it, the pen moves the cursor, but neither the
buttons nor the tap sensor in the tip do work.

HID: hid-uclogic-params: Invalid parameter check in uclogic_params_frame_init_v1_buttonpad

[ Upstream commit aa320fdbbbb482c19100f51461bd0069753ce3d7 ]

The function performs a check on the hdev input parameters, however, it
is used before the check.

Initialize the udev variable after the sanity check to avoid a
possible NULL pointer dereference.

HID: wacom: Avoid using stale array indicies to read contact count

2022-01-27T08:19:26+00:00

commit 20f3cf5f860f9f267a6a6e5642d3d0525edb1814 upstream.

If we ever see a touch report with contact count data we initialize
several variables used to read the contact count in the pre-report
phase. These variables are never reset if we process a report which
doesn't contain a contact count, however. This can cause the pre-
report function to trigger a read of arbitrary memory (e.g. NULL
if we're lucky) and potentially crash the driver.

This commit restores resetting of the variables back to default
"none" values that were used prior to the commit mentioned
below.
