From: Benjamin Tissoires <redacted> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit a80e803a2ae4efa5efbcfa97dcbbc48d15226cf9 upstream. The firmware found in the touch screen of an SP3 is buggy and may miss to send lift off reports for contacts. Try to work around that issue by using MT_QUIRK_NOT_SEEN_MEANS_UP. based on a patch from: Daniel Martin [off-list ref] Signed-off-by: Benjamin Tissoires <redacted> Signed-off-by: Jiri Kosina <redacted> Cc: Oliver Neukum <oliver@neukum.org> Signed-off-by: Jiri Slaby <redacted> --- drivers/hid/hid-multitouch.c | 5 +++++ 1 file changed, 5 insertions(+)
