This means that the caller of __pm_runtime_resume() did something odd.

In this particular case usbhid_power() probably shouldn't have called
pm_runtime_get_sync() or it shouldn't have been called itself or
similar.

Hi Rafael,
This report is caused by a major memory corruption that can lead to
all kinds of weird things. Let's wait for the fix to be in the
mainline and then see if these bugs are still occurring.
Thanks!
