+Subject: tpm: ibmvtpm: Correct the return value in tpm_ibmvtpm_probe()
+
+From: Xiu Jianfeng <xiujianfeng@huawei.com>
+
+commit d0dc1a7100f19121f6e7450f9cdda11926aa3838 upstream.
+
+Currently it returns zero when CRQ response timed out, it should return
+an error code instead.
+
+Fixes: d8d74ea3c002 ("tpm: ibmvtpm: Wait for buffer to be set before proceeding")
