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. Signed-off-by: Alison Chaiken <alison_chaiken@mentor.com> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
