Subject: [PATCH v4 0/2] ibmvtpm: Avoid error message when process gets signal while waiting

From: Stefan Berger <stefanb@...ux.ibm.com>

This series of patches fixes an issue related to the ibmvtpm driver causing
unnecessary kernel log messages when a process is interrupted while waiting
for the TPM to respond. The aborted wait causes the core TPM driver to emit
the log message. The solution is to convert the driver to use the normal
polling loop to wait for TPM responses.
