Comment(by martin.langhoff):

 To get more certainty re the provided patch, I traced it in the Ubuntu
 kernel tree. The commit is in http://kernel.ubuntu.com/git?p=ubuntu

 It is indeed a mash of 2 commits currently in Linus' tree:

  * "Input: elantech - use firmware provided x, y ranges" cherry-picks with
 resolvable minor conflicts
  * An early version of "Input: elantech - add v3 hardware support" --
 which seems to have gotten a serious cleanup before landing upstream.
 Unfortunately, there is a non-trivial delta of unrelated changes that
 prevents a clean cherry pick of the upstream patch.

 Will merge using the Ubuntu patch which has better commit message.

 Future kernels have a cleaner version of the same logic, we don't expect
 that we'll need to rebase or reapply any patches here going forward.

 Unfortunately, documentation in elantech.txt does not cover tweaking
 acceleration and seems out of date.
