dt-bindings: fix error in 'make clean' after 'make dt_binding_check'
We are having more and more schema files. Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit calling dt-mk-schema") fixed the 'Argument list too long' error of the schema checks, but the same error happens while cleaning too. 'make clean' after 'make dt_binding_check' fails as follows: $ make dt_binding_check [ snip ] $ make clean make[2]: execvp: /bin/sh: Argument list too long make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127 make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2 make: *** [Makefile:1763: _clean_Documentation] Error 2 'make dt_binding_check' generates so many .example.dts, .dt.yaml files, which are passed to the 'rm' command when you run 'make clean'. I added a small hack to use the 'find' command to clean up most of the build artifacts before they are processed by scripts/Makefile.clean Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Link: https://lore.kernel.org/r/20200625170434.635114-2-masahiroy@kernel.org Signed-off-by: Rob Herring <robh@kernel.org>
