Subject: [PATCH] obsolete config in kernel source (HSO_AUTOPM)

Hi all!

As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

This is just a one-liner commented out unconditionally (due to
the config not existing) and being like this for virtually ever so I'm
suggesting to remove it from the kernel tree.

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

Regards

Christoph Egger

Subject: [PATCH] Remove unreferenced HSO_AUTOPM

CONFIG_HSO_AUTOPM is set by KConfig / set in the Kernel source,
makefiles and won't be ever set this way, therefor simply removing the
protected code.
