Subject: drm: omapdrm: acx565akm: Remove unneeded check for OF node
Git-commit: fb8862fa03afcce8f0cf66a06c4ea8fa819f64e4
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

As non-DT booting is no longer supported, the only way to instantiate
the device is through an OF node, which is guaranteed to be present.
Remove the unneeded check.
