The above code seems risky, as it could be doing an endless loop
that would starve the CPU.
You should, instead, use a wait queue or some other logic that would
not keep the CPU on some endless loop if something bad happens.

Why do you need a define here? Where such symbol is defined?
If there's a good reason for the ifdef, then you would likely need to
add it at Kconfig.
Also, if such option is really required, IMO, the best would be to
split the part of the code inside the ifdefs into two separate
inline implementation at the header file and put the #ifdef there,
as having ifdefs inside the code makes it harder to review.

This s a general note: do you really need tracing-like debug macros
all around the code?
You could easily check if the functions are called via trace.

You could put it into just one line.
Yet, I don't see a reason to inform that the module is being
probed. Instead, it would make sense to inform that the module
was successfully probed, or if it failed for some reason
different than -ENOMEM (as this specific error is already
reported by the core).
