DT_SCHEMA_FILES used to allow specifying a space separated list of file paths, but the introduction of partial matches support broke this feature: $ make dtbs_check DT_SCHEMA_FILES="path/to/schema1.yaml path/to/schema2.yaml" [...] LINT Documentation/devicetree/bindings usage: yamllint [-h] [-] [-c CONFIG_FILE | -d CONFIG_DATA] [--list-files] [...] [-v] [FILE_OR_DIR ...] yamllint: error: one of the arguments FILE_OR_DIR - is required [...] Restore the lost functionality by preparing a grep filter that is able to handle multiple search patterns. Additionally, as suggested by Rob, use ':' instead of ' ' as the patterns separator char. Hence, the command above becomes: $ make dtbs_check DT_SCHEMA_FILES="path/to/schema1.yaml:path/to/schema2.yaml" Fixes: 309d955985ee ("dt-bindings: kbuild: Support partial matches with DT_SCHEMA_FILES") Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@collabora.com> Link: https://lore.kernel.org/r/20230209193735.795288-1-cristian.ciocaltea@collabora.com Signed-off-by: Rob Herring <robh@kernel.org>
