After adding this patch, the unittest messages will show: Duplicate name in motor-1, renamed to "controller#1" OF: overlay: of_overlay_apply() err=0 ### dt-test ### of_overlay_fdt_apply() expected -22, ret=0, overlay_bad_add_dup_node ### dt-test ### FAIL of_unittest_overlay_high_level():2419 Adding overlay 'overlay_bad_add_dup_node' failed ... ### dt-test ### end of unittest - 210 passed, 1 failed The incorrect (munged) node name "controller#1" can be seen in the /proc filesystem: $ pwd /proc/device-tree/testcase-data-2/substation@100/motor-1 $ ls compatible controller controller#1 name phandle spin $ ls controller power_bus $ ls controller#1 power_bus_emergency Tested-by: Alan Tull <atull@kernel.org> Signed-off-by: Frank Rowand <frank.rowand@sony.com> |
