Is this error related to the binder driver update?

Searching around, it seems that this could cause a higher battery drain, which I did experience after the latest update. I'm on VanirKK, and now the drain could be around 10%/h on minimum usage. Previously it was only 2-4%/h.

Update:

Cross-checking with the pid, it happens to most application, mostly those that could cause cpu spikes.
