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
