Subject: PM / Domains: Fix unsafe iteration over modified list of device links
From: Krzysztof Kozlowski <[email protected]>
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.
