WiFi not working with linaro-sid-alip-dragonboard-820c-509.img

Hi, all,
I use linaro-sid-alip-dragonboard-820c-509.img, but wifi pcie cannot link up.

[ 3.576287] qcom-pcie 600000.qcom,pcie: Unbalanced pm_runtime_enable!

Is there any suggestion about this issue?
Thanks!

Those error messages seem to be coming from an old kernel. You should also have flashed boot-linaro-sid-dragonboard-820c-509.img.
