[PATCH v2] Kernel selftests: Add check if tpm devices are supported

From: Nikita Sobolev
Date: Tue May 19 2020 - 08:08:27 EST


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.
