crypto: nx - reduce chattiness of platform drivers
While we never would successfully load on the wrong machine type, there is extra output by default regardless of machine type. For instance, on a PowerVM LPAR, we see the following: nx_compress_powernv: loading nx_compress_powernv: no coprocessors found even though those coprocessors could never be found.
