Yet another nightmare for out-of-tree modules that aim at supporting multiple kernel versions. sigh...

Unused parameters are undesirable.

If the module is added to the kernel the porting will be done for you. Plus the various kernel versions automatically will either have or won't have that parameter.

Or in other words: pretty well known that there is no stability guarantee and the developers prefer to include your module/driver in the kernel. Seems that this often also gets you a good review (thus better quality).
