What's wrong with: #1 - These additional tests have the following failures which are fixed in subsequent commits: ... #2 - This commit fixes these unittest failures: ... #3 - This commit fixes these unittest failures: ... 2 and 3 already do that. So if you are assuming they are all applied together, then why summarize the whole series in patch 1? >> And 1 and 2 are probably stable material?

I'd hope that is all outside the core DT code though. But okay by me if not tagged for stable. >>> Console error message near end of unittest: >>> OF: Duplicate name in fairway-1, renamed to "ride@100#1" >>> >>> $ cd /proc/device-tree/testcase-data-2/fairway-1/ >>> $ # extra node: ride@100#1 >>> $ ls >>> #address-cells linux,phandle phandle ride@200 >>> #size-cells name ride@100 status >>> compatible orientation ride@100#1 >>> $ cd /proc/device-tree/testcase-data-2/fairway-1/ride@100/ >>> $ ls track@3/incline_up >>> ls: track@3/incline_up: No such file or directory >>> $ ls track@4/incline_up >>> ls: track@4/incline_up: No such file or directory >> >> [...] >> >>> diff --git a/drivers/of/unittest-data/Makefile b/drivers/of/unittest-data/Makefile >>> index 6e00a9c69e58..dae2fe23cd2e 100644 >>> --- a/drivers/of/unittest-data/Makefile >>> +++ b/drivers/of/unittest-data/Makefile >>> @@ -1,11 +1,13 @@ >>> obj-y += testcases.dtb.o >>> obj-y += overlay.dtb.o >>> obj-y += overlay_bad_phandle.dtb.o >>> +obj-y += overlay_bad_symbol.dtb.o >>> obj-y += overlay_base.dtb.o >> >> There's no reason for these all to be 1 per line. > > OK.
