The error logging for tpm2_commit_space() is in a wrong place. This
commit moves it inside that function.

This is in tpm-interface.c:

ÂÂÂ rc = tpm2_commit_space(chip, space, ordinal, buf, &len);
ÂÂÂ if (rc)
ÂÂÂ ÂÂÂ dev_err(&chip->dev, "tpm2_commit_space: error %d\n", rc);

I suppose you will remove if(rc) ... ?
