3.16.49-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <k...@kernel.org>
commit c6e83cac3eda5f7dd32ee1453df2f7abb5c6cd46 upstream.
pm_genpd_remove_subdomain() iterates over domain's master_links list and
removes matching element thus it has to use safe version of list
iteration.
Fixes: f721889ff65a ("PM / Domains: Support for generic I/O PM domains (v8)")
