Subject: [PATCH v2 0/8] PM / Domains: Bunch of small improvements and fixes

Hi,

Changes since v1:
=================
1. Patch 2/8: Follow Ulf's advice and use genpd_lookup_dev() which also
   solves risk of calling this for non-genpd (thus I added Ulf's
   Reported-by).

Description:
============
Except adding lockdep assert to domains list mutex (3/8), all patches
are independent.  Including the fixes for unsafe loop iteration.

The last patch is RFC as this brings small overhead.

Best regards,
Krzysztof
