Viresh Kumar 09b63105d0 opp: Prevent memory leak in dev_pm_opp_attach_genpd() ... [ Upstream commit cb60e9602c ] If dev_pm_opp_attach_genpd() is called multiple times (once for each CPU sharing the table), then it would result in unwanted behavior like memory leak, attaching the domain multiple times, etc. Handle that by checking and returning earlier if the domains are already attached. Now that dev_pm_opp_detach_genpd() can get called multiple times as well, we need to protect that too. Note that the virtual device pointers aren't returned in this case, as they may become unavailable to some callers during the middle of the operation.
