I was on vacation last week, so couldn't respond earlier, sorry.

As you noticed, 204d49a56 removed some acpi_walk_namespace() calls.
It removed calls to the old "pre-order only" version, while 263576cfc
converted acpi_walk_namespace() to a new "pre-order and post-order"
version.

This is conceptually simple because 204d49a56 is just removing uses
of acpi_walk_namespace(), so we don't care at all whether it removes
calls to the old or new version.  But I don't have enough git-fu to
know how to fix this.
