The snippet in question:
rc = chip->ops->send(chip, buf, count);
if (rc < 0) {
if (rc != -EPIPE)
dev_err(&chip->dev,
"%s: tpm_send: error %d\n", __func__, rc);
return rc;
}
if (chip->flags & TPM_CHIP_FLAG_IRQ)
goto out_recv;
'send()' ought to return zero on success case.
This is how the snippet was before applying any patches scheduled for
v5.1:
rc = chip->ops->send(chip, buf, count);
if (rc < 0) {
if (rc != -EPIPE)
dev_err(&chip->dev,
"%s: tpm_send: error %d\n", __func__, rc);
return rc;
}
if (chip->flags & TPM_CHIP_FLAG_IRQ)
goto out_recv;
Does not compute.
