Most of them seem to return from probe calls etc. Is there a nice way to make sure the second level functions and the callers of those are not using -ENOTSUPP return from these functions. >Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> > Thanks. -- Lina >Kind regards >Uffe > >> --- >> include/linux/pm_domain.h | 14 +++++++------- >> 1 file changed, 7 insertions(+), 7 deletions(-) >> >> diff --git a/include/linux/pm_domain.h b/include/linux/pm_domain.h >> index 49982cd58bfd..e390388e6c17 100644 >> --- a/include/linux/pm_domain.h >> +++ b/include/linux/pm_domain.h >> @@ -259,24 +259,24 @@ static inline int pm_genpd_init(struct generic_pm_domain *genpd, >> } >> static inline int pm_genpd_remove(struct generic_pm_domain *genpd) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline int dev_pm_genpd_set_performance_state(struct device *dev, >> unsigned int state) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline int dev_pm_genpd_add_notifier(struct device *dev, >> struct notifier_block *nb) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline int dev_pm_genpd_remove_notifier(struct device *dev) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline int dev_pm_genpd_set_next_wakeup(struct device *dev, ktime_t next) >> @@ -334,13 +334,13 @@ struct device *genpd_dev_pm_attach_by_name(struct device *dev, >> static inline int of_genpd_add_provider_simple(struct device_node *np, >> struct generic_pm_domain *genpd) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline int of_genpd_add_provider_onecell(struct device_node *np, >> struct genpd_onecell_data *data) >> { >> - return -ENOTSUPP; >> + return -EOPNOTSUPP; >> } >> >> static inline void of_genpd_del_provider(struct device_node *np) {} >> @@ -396,7 +396,7 @@ static inline struct device *genpd_dev_pm_attach_by_name(struct device *dev, >> static inline >> struct generic_pm_domain *of_genpd_remove_last(struct device_node *np) >> { >> - return ERR_PTR(-ENOTSUPP); >> + return ERR_PTR(-EOPNOTSUPP); >> } >> #endif /* CONFIG_PM_GENERIC_DOMAINS_OF */ >> >> -- >> The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, >> a Linux Foundation Collaborative Project >>

Good question. But I can't think of one (besides code inspection) - unless you have a running system. > > >Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Anyway, let's give this a try and see what happens!
