Subject: evdev: set CLOCK_MONOTONIC as the time source
X-Git-Tag: 0.1.0~7^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=84c4f40f25e91ff6ecd35b47398d13ac3996f101;p=platform%2Fupstream%2Flibinput.git

evdev: set CLOCK_MONOTONIC as the time source

Avoids erroneous timestamps when the system time is reset. This used to a be a
problem with the X.Org synaptics driver where taps, scrolling and a couple of
other things would potentially lock up.
