From 4fcac10d28e7a046120b51a106b19082d2e57401 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Mon, 7 May 2012 21:35:45 +0200 Subject: [PATCH] PM / Domains: Fix link checking when add subdomain Current pm_genpd_add_subdomain() will allow duplicated link between master and slave domain. This patch fixed it. Because when current pm_genpd_add_subdomain() checks whether the link between the master and slave generic PM domain already exists, slave_links instead of master_links of master domain is used.
