I'm not really sure that we need this macro, but I don't really object either. As long as it has callers I guess it's fine, I just don't want <linux/pm.h> to become too bloated and confusing.

Isn't theidea behind all helpers to simplify life of the users by the cost of bloaring up (a bit) the common file (header and/or C file)? As cover letter shows, despite having several LoCs added to the pm.h we saved already a few dozens of LoCs. And this it not the end, there are more users can come. Moreover, there are some deprecated macros and those that starts with SET_*(). Removing them can make balance go too negative for the pm.h (in terms of +- LoCs). So I can't really consider above as argument. > Anyway: > Reviewed-by: Paul Cercueil <paul@crapouillou.net> Thank you!

_DEFINE_DEV_PM_OPS() helps to define PM operations for the system sleep and/or runtime PM cases. Some of the existing users want to have _noirq() variants to be set. For that purpose introduce a new helper which sets up _noirq() callbacks to be set and struct dev_pm_ops be provided.
