This is wrong and even if it wasn't the ltp_acpi_cmd.ko is covered by
the *.ko bellow.
Ah, yes, but it's .*.ko (it doesn't match ltp_apci_cmd.ko), so I still have to add it with the right name.

The same goes for the tst_resm() here.

I would write this part so that reading the sys_str file triggers
walking to next object with _STR argument, while writing to dev_tcase
will reset the walk to root and wrote a code as:

        SAFE_FILE_PRINTF(cleanup, dev_tcase, "%d", i);
        SAFE_FILE_SCANF(cleanup, dev_result, "%d", &res);

        if (i == ACPI_TRAVERSE)
                res = next_acpi_str();

        tst_resm(...);

And the next_acpi_str() would loop on reading the dev_str while "null"
is returned. Or even better make the read returns zero size at the end,
(should be mapped to EOF in case of FILE*).
OK
Also I would be more carefull and rather sanitized the result value, i.e.

        tst_resm(ret ? TFAIL : TPASS, "...");
If I do that way, next_acpi_str could also return TCONF (kernel version lower than 3.7) and then we would get TFAIL in the test-case result.
