Add CONFIG_PM_SLEEP to suspend/resume functions Add CONFIG_PM_SLEEP to suspend/resume functions instead of CONFIG_PM to fix the following build warning when CONFIG_PM_SLEEP is not selected and CONFIG_PM is selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled.Recently I've become a fan of __maybe_unused markings as they insulate us from various CONFIG changes in unrelated subsystems, I'll transform this patch to use them instead.OK, I see. I have no objection. Then, how about changing other usages of CONFIG_PM_SLEEP/CONFIG_PM to __maybe_unused annotation? Personally, I prefer to increase build coverage than using #ifdef guards. Someone, however, argued that #ifdef guards should be used in this case because the size of binary can be reduced. How about your opinion?The optimizer is supposed to drop functions marked as '__maybe_unused' if they are indeed unused so size of the binary should not change.Oh, I really appreciate your reply. :-) Then, how about changing other usages of CONFIG_PM_SLEEP/CONFIG_PM to __maybe_unused annotation? If you don't have any objection, I will send one single patch for this.
That will work. Thanks. -- Dmitry
