[Po-Hsu Lin]

Verified on:
201302-12843, 201302-12844 (Dell Latitude 3330)
201208-11536 (Dell Latitue 6430U)
Steps:
1. Install 12.04.2 stock Ubuntu and boot to desktop.
2. Test if keyboard works as expected.
3. Press the "disable touchpad" hotkey (Fn+F3).
4. Test if keyboard works as expected.
5. Enable -porposed, and install the proposed udev (175-0ubuntu9.4).
6. Reboot.
7, Repeat step 2,3,4

Expected Result:
1. Keyboard should work before pressing the hotkey.
2. Keyboard should not work after pressing the hotkey.
3. Keyboard should work with the proposed udev installed, whether the hotkey were pressed or not.

Actual Result:
It works as expected.

Summary: 
This fix works, thanks!

Title:
  [keymap] Touchpad key broken on Dell Latitude 6430U and 3330

Status in HWE Next Project:
  In Progress
Status in “systemd” package in Ubuntu:
  Fix Released
Status in “udev” package in Ubuntu:
  Invalid
Status in “udev” source package in Precise:
  Fix Committed

Bug description:
  Precise's udev package doesn't detect that the Dell Latitude 6430U or
  3330 need keyboard force release synthesis. This causes undesirable
  behavior on these two systems. Quantal and upstream udev have an
  updated rule to handle the 6430U. Neither have such a rule to handle
  the 3330. We only ship Ubuntu pre-load systems with an LTS release
  installed, so the fix needs to be in Precise. Here is a patch to
  address both.
