From 740ce365a4dccc1df4d05219cd5bf68f01359196 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 30 Jul 2019 08:49:34 -0600 Subject: [PATCH 1/5] dt-bindings: Fix generated example files getting added to schemas MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 837158b847a4 ("dt-bindings: Check the examples against the schemas") started generating YAML encoded DT files to validate the examples against the schema. When running 'make dt_binding_check' in tree after the 1st time, the generated example .dt.yaml files are mistakenly added to the list of schema files. Exclude *.example.dt.yaml files from the search for schema files.

Hence add an of_node_put before the return or break in three places. Issue found with Coccinelle.
