From 75bda95048a4d2c5ff04036bd0181bc84085d8b2 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Tue, 9 May 2017 13:17:08 +1000 Subject: [PATCH] powerpc: Don't print cpu_spec->cpu_name if it's NULL Currently we assume that if the cpu_spec has a pvr_mask then it must also have a cpu_name. But that will change in a subsequent commit when we do CPU feature discovery via the device tree, so check explicitly if cpu_name is NULL.
