From d7e82b903dbd5f0295dad4a807ae1faf4ed5461e Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Mon, 12 Nov 2018 12:25:25 +0000 Subject: slimbus: ngd: Fix build error on x86 [ Upstream commit 458a445deb9c9fb13cec46fe9b179a84d2ff514f ] on non DT platforms like x86 of_match_node is set to NULL, dereferencing directly would throw an error. Fix this by doing this in two steps, get the match then the data.
