2016-09-27HID: alps: fix multitouch cursor issueMasaki Ota1-6/+6
Issue reproduction procedure: 1. three or more fingers put on Touchpad. 2. release fingers from Touchpad. 3. move the cursor by one finger. 4. the cursor does not move. Cause: We do not notify multi fingers state correctly to input subsystem. For example, when three fingers release from Touchpad, fingers state is 3 -> 0. It needs to notify first, second and third finger's releasing state. Fix this by not breaking out on z axis and move x,y,z input handling code to the correct place so that it's in fact per-finger.

2016-09-22HID: alps: fix stick device not working after resumeKai-Heng Feng1-2/+2
The stick device does not work after resume, add U1_SP_ABS_MODE flag can make the device work after resume. This has been discovered by pure guesswork, based on how the existing code uses U1_TP_ABS_MODE flag on both initialization and resume. I also tested the the patch on an ALPS touchpad without stick device, did not notice any side effect on suspend/resume, so I made the U1_SP_ABS_MODE flag mandatory.
