[PATCH] sparc64: Limit nvme of_path_of_nvme to just SPARC

From: Eric Snowberg
Subject: [PATCH] sparc64: Limit nvme of_path_of_nvme to just SPARC
Date: Thu, 1 Mar 2018 19:25:09 -0800

Limit NVMe of_path_of_nvme to just SPARC hardware for now.  It has been
found that non-Open Firmware hardware platforms can some how access
this function.

Signed-off-by: Eric Snowberg <address@hidden>

  This patch should be applied after Adrian's "ieee1275: Fix crash in 
  of_path_of_nvme when of_path is empty" patch
