If any client drivers use devm_pm_domain_attach_list() to attach the PM domains, devm_pm_domain_detach_list() will be invoked implicitly during remove phase. Changes since v3: - updated null check for num_pds to num_pds <=0. Changes since v2: - made devm_pm_domain_detach_list as static and no longer export this API. - added null checks for num_pds to avoid adding a devres callback for the same. - added bryan's reviewed-by from v1. Changes since v1: - fixed the warnings reported by kernel test robot. - added stub functions for !CONFIG_PM case. - removed un-necessasry type casting. - fixed the issue with remove sequence.
