[ Upstream commit6359691b4f] TPM2 sessions have been flushed lazily since commitdf745e2509("tpm: Lazily flush the auth session"). If /dev/tpm{rm}0 is not accessed in-between two in-kernel calls, it is possible that a TPM2 session is re-started before the previous one has been completed. This causes a spurios warning in a legit run-time condition, which is also correctly addressed with a fast return path: [ 2.944047] tpm tpm0: auth session is active Address the issue by changing dev_warn_once() call to a dev_dbg_once() call. [jarkko: Rewrote the commit message, and instead of dropping converted to a debug message.] Signed-off-by: Jonathan McDowell <noodles@meta.com> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
