From 52c47b63412b0946fcf3c04b5e152df41fc7eca5 Mon Sep 17 00:00:00 2001 From: Alison Chaiken Date: Wed, 18 Feb 2015 23:24:10 -0800 Subject: bus: imx-weim: improve error handling upon child probe-failure Probe all children of the WEIM node, reporting any failures. Report failure from parsing of WEIM node itself if probes of all children fail.
