6.11-stable review patch. If anyone has any objections, please let me know.

From: Jarkko Sakkinen jarkko@kernel.org
commit 423893fcbe7e9adc875bce4e55b9b25fc1424977 upstream.
The earlier bug fix misplaced the error-label when dealing with the tpm2_create_primary() return value, which the original completely ignored.
