Hi Mark, Yes there is one for the cs_dsp_init_debugfs function though the compilation failure the bot detected is with the parameter dereferencing the disappearing snd_soc_component member. I could make a utility inline for use in this function that would do the dereference or return NULL based on the state of the config option if you think that would be neater? (For the expense of a new function it would separate the call of the stub from the conditional access of the member based on IS_ENABLED) Thanks, Simon
