I try to use the new marcos SYSTEM_SLEEP_PM_OPS and RUNTIME_PM_OPS to
replace the old ones, and remove #ifdef around the declarations in the
header, my local changes attach below.
But it seems that doesn't work, which has ld errors:

(CONFIG_PM and CONFIG_PM_SLEEP are both not set, and
It appears that there is a mistake in the RUNTIME_PM_OPS()
macro definition, can you try this patch on top?
Hi Arnd,
I apply this patch and it worked.
When will this patch be merged?
Thanks,
Ren

Commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate
old ones") introduced all the macros with the intent of using pm_ptr()
and pm_sleep_ptr() in them, and I think Paul accidentally forgot to add
those in this instance.
