Which as far as I can tell has nothing to do with this specific wakelock, which sometimes causes my phone to never go into deep sleep.
Yes, maps is obnoxious and causes plenty of its own wakelocks, but if mdm_hsic_pm0 is keeping my phone awake 100% of the time it's pretty irrelevant.
I was simply analyzing the information provided and giving suggestions.
On a related note, the times I've seen this wakelock the highest were when I had GPS enabled all day. I typically leave GPS off, it's a battery killer in low-service areas.
