The empty message turned me into suspicious mode, and I took another look
at the patch... :-)

Why? This basically reverts recent change:

commit ec511672b97383107d87e86921b1f0392bc1d000
Author: Linus Walleij <linus.walleij@...aro.org>
Date:   Fri Apr 13 10:16:06 2012 +0200

    ab8500_btemp: Harden platform data check

..and other commits from Linus' series.

The patch description doesn't tell anything why this is no longer needed.

This is surely stray change.

These seem like stray changes too. At least I don't see how you the new
members in this patch.
