Subject: kbuild: fix DT binding schema rule again to avoid needless rebuilds
From: Masahiro Yamada <masahiroy@xxxxxxxxxx>
commit 3d4b2238684ac919394eba7fb51bb7eeeec6ab57 upstream.
Since commit 7a0496056064 ("kbuild: fix DT binding schema rule to detect
command line changes"), this rule is every time re-run even if you change
nothing.
cmd_dtc takes one additional parameter to pass to the -O option of dtc.
We need to pass 'yaml' to if_changed_rule. Otherwise, cmd-check invoked
from if_changed_rule is false positive.
Fixes: 7a0496056064 ("kbuild: fix DT binding schema rule to detect command line changes")
