As I said on another email, no, please do not add new module parameters
for drivers, this is not the 1990s

Also, another comment below:

Only ever use likely/unlikely if you can measure the difference.  Here
on a probe function, you can not, this is not needed at all, the
compiler and CPU will do a better job over time than you can guess at
this.

But as this change isn't needed, this shouldn't be an issue either.
