[PATCH] Missmatch between source and Kconfig for ACPI && !PM

[Christoph Egger]

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

	There's a check for CONFIG_PM inside a block that is only
compiled if CONFIG_ACPI is set. As CONFIG_ACPI depends on CONFIG_PM
the check is currently redundant, the Code always active and it's else
branch always dead.

	The attached patch takes the naive solution and only makes it
clearer how this source is handled currently. However if the
combination ACPI && !PM is usefull the depends in Kconfig might need
to be lowered.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger
