From 2b93f7ee0836d1dbcfcf8560dd2a34cd51b3ff21 Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Mon, 6 Jul 2015 10:06:21 -0700 Subject: [PATCH] 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.
