tpm2 tests set uses /dev/tpm0 and /dev/tpmrm0 without check if they
are available. In case, when these devices are not available test
fails, but expected behaviour is skipped test.

Thanks for v2, but I see v1 already merged in next tree since February.

OK, I see it was also reverted by Jarkko

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20200518&id=aaa2d92efe1f972567f1691b423ab8dc606ab3a9

I wonder if only wrong shell syntax (self.flags = flags) is a problem.

Kind regards,
Petr

See

The comments about the fixes tag and acronym spelling were not
addressed. The code change looks great tho now, thanks.
