commit 16871dcac74c (usb_wwan: error case of resume) added a build error
if CONFIG_PM_RUNTIME is not defined.

  CC [M]  drivers/usb/serial/usb_wwan.o
drivers/usb/serial/usb_wwan.c: In function ‘play_delayed’:
drivers/usb/serial/usb_wwan.c:702: error: ‘struct dev_pm_info’ has no
member named ‘usage_count’

I suspect we should use pm_runtime_put_noidle() instead

Yes. I don't understand why it compiled for me. Has it been removed?

usage_count is only there when CONFIG_PM_RUNTIME is enabled.
Building with CONFIG_PM_RUNTIME disabled produces a build error.
