Seems ok to me. These files, and functions, are also in drivers/staging/dream/ are you removing them there also ?

Hi My script looks for the same function name, so if they then would be named exactly the same, they would come up. But I can not even find drivers/staging/dream/ or is this really new code?

It's been gone for over four years, after nobody worked on cleaning it up for a while before that: commit 3414df8ca38b203c8a5ad8efc32d4a3836a0596d Author: Greg Kroah-Hartman <gregkh@suse.de> Date: Fri Oct 29 12:42:18 2010 -0700 Staging: dream: remove dream driver and arch from tree This code is stalled, with no one working on it anymore, and the main msm code is now going through the proper channels to get merged correctly. So remove it as it contains a number of kernel information leaks and it is doubtful if it even still builds anymore.
