[PATCH 1/5] kbuild: fix DT binding schema rule to detect command line changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This if_change_rule is not working; it cannot detect any command line
changes.

The reason is because cmd-check in scripts/Kbuild.include compares
$(cmd_$@) and $(cmd_$1), but cmd_dtc_dt_yaml does not exist here.

For if_change_rule to work properly, the stem part of cmd_* and rule_*
must match. Because this cmd_and_fixdep invokes cmd_dtc, this rule must
be named rule_dtc.
