From 6d186bceac74dd7fcabac860295cfb7b893168cd Mon Sep 17 00:00:00 2001

Subject: [PATCH] crypto: caam - populate platform devices last
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the call to devm_of_platform_populate() at the end of
caam_probe(), so we won't try to add any child devices until all of
the initialization is finished successfully.
