kbuild: check libyaml installation for 'make dt_binding_check'
If you run 'make dtbs_check' without installing the libyaml package, the error message "dtc needs libyaml ..." is shown. This should be checked also for 'make dt_binding_check' because dtc needs to validate *.example.dts extracted from *.yaml files. It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT binding schema checks"), but this fix-up is applicable only after commit e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check in a single command"). I gave the Fixes tag to the latter in case somebody is interested in back-porting this. Fixes: e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check in a single command") Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Rob Herring <robh@kernel.org>
