From df58f37b5d8f883fb18ba85e8d9a624154879832 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 29 Aug 2018 15:03:37 -0500 Subject: sbus: Use of_get_child_by_name helper Use the of_get_child_by_name() helper instead of open coding searching for the '/options' node. This removes directly accessing the name pointer as well. Cc: "David S. Miller" Cc: sparclinux@vger.kernel.org Signed-off-by: Rob Herring Signed-off-by: David S.
