pm-5.0-rc5

 - Since ktime_get() turns out to be problematic for device
   autosuspend in the PM-runtime framework, make it use
   ktime_get_mono_fast_ns() instead (Vincent Guittot).

 - Fix an initial value of a local variable in the "poll idle state"
   code that makes it behave not exactly as expected when all idle
   states except for the "polling" one are disabled (Doug Smythies).
