Subject: Re: [git pull] Input updates for 3.18-rc4

I'm not sure if my problems are related, but anyway:

I'm using a Samsung NP730U3E notebook that also has an elantech touchpad.

With 3.18.0-rc3 two finger scrolling in Firefox is smoth, but with
3.18.0-rc5 I have to press a
lot harder and usually scrolling only startes after stopping the
movement shortly and retrying once

I skipped rc4.

from RC3 dmesg:
[   20.507633] psmouse serio1: elantech: assuming hardware version 4
(with firmware version 0x675f04)
[   20.520740] psmouse serio1: elantech: Synaptics capabilities query
result 0x10, 0x15, 0x0e.

regards
Marcus
