Subject: [PATCH 1/2] kbuild: fix DT binding schema rule again to avoid needless rebuilds
Date: Tue, 21 Apr 2020 12:35:28 +0900 [thread overview]
Message-ID: <20200421033529.487366-1-masahiroy@kernel.org> (raw)
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")
