Stefan Berger 22de4a5d57 tpm: ibmvtpm: Wait for buffer to be set before proceeding ... [ Upstream commit d8d74ea3c0 ] Synchronize with the results from the CRQs before continuing with the initialization. This avoids trying to send TPM commands while the rtce buffer has not been allocated, yet. This patch fixes an existing race condition that may occurr if the hypervisor does not quickly respond to the VTPM_GET_RTCE_BUFFER_SIZE request sent during initialization and therefore the ibmvtpm->rtce_buf has not been allocated at the time the first TPM command is sent.
