Thanks for forwarding, Paul. AFAICS, the comment is a false positive.

My theory is that Gemini conflates two different variables named
'space':

1. The 'space' parameter passed to tpm_dev_transmit(). This *can* be
   NULL (it is NULL for /dev/tpm0 clients).

2. The local 'space' variable inside tpm2_flush_space(). This is
   assigned from &chip->work_space and can *never* be NULL.

The removed NULL check was testing case (2), not case (1).
