touchpad stops working after suspend/resume on XPS13 2015

Assuming vivid will have kernel 3.19 or later, vivid task is Fix Released.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-utopic' to 'verification-done-utopic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I have verified Linux kernel 3.16.0-31-generic and it does fix this issue.

This bug was fixed in the package linux - 3.16.0-31.41
