USB-related lock inversion complaint

Hello, Every time I boot a particular development server the complaint shown below appears in the system log. I don't know when this behavior has been introduced. But I noticed that I can reproduce this with older kernel versions, e.g. 4.4.63. Does anyone know what is going on or how to fix this?
