Jason Gerecke df03e9bd6d HID: wacom: Ignore the confidence flag when a touch is removed ... AES hardware may internally re-classify a contact that it thought was intentional as a palm. Intentional contacts are reported as "down" with the confidence bit set. When this re-classification occurs, however, the state transitions to "up" with the confidence bit cleared. This kind of transition appears to be legal according to Microsoft docs, but we do not handle it correctly. Because the confidence bit is clear, we don't call `wacom_wac_finger_slot` and update userspace. This causes hung touches that confuse userspace and interfere with pen arbitration. This commit adds a special case to ignore the confidence flag if a contact is reported as removed. This ensures we do not leave a hung touch if one of these re-classification events occured. Ideally we'd have some way to also let userspace know that the touch has been re-classified as a palm and needs to be canceled, but that's not possible right now :) Link: https://github.com/linuxwacom/input-wacom/issues/288 Fixes: 7fb0413baa (HID: wacom: Use "Confidence" flag to prevent reporting invalid contacts) CC: stable@vger.kernel.org Signed-off-by: Jason Gerecke <jason.gerecke@wacom.com> Reviewed-by: Ping Cheng <ping.cheng@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>		2022-01-21 15:10:02 +01:00
