I hit something similar while testing some of the qcom sound card.

This patch fixed the issue for me:

 
https://git.linaro.org/people/srinivas.kandagatla/linux.git/commit/?h=v4.16-rc1-dsp-audio-v3&id=b91fa95c38912dd8a9f56ebdb9b59449252798ef

Its basically to do with nested device tree nodes, the device name seems 
to exceed the NAME_SIZE of 32 bytes.


thanks,
