I'm fine with that, but it was originally your code from
the first ssb commit in 2007:

This might only be desired for production kernels on
embedded devices to reduce the kernel size.

Presumably for ddwrt and such.

Removal could simplify the ssb_<foo> printk logic a bit too.

Perhaps something like the below,
but your code, your decisions...:
