Jarkko, w.r.t your comment above, there is an empty line between the function name and variables in drivers/char/tpm, and in particular tpm_crb.c which you authored and I used as reference. Do you want us to diverge here?
There is divergence and that was the first thing I've contributed to the TPM driver. I use this as the reference for formatting function descriptions these days:
https://www.kernel.org/doc/Documentation/kernel-doc-nano-HOWTO.txt
According to that the legit way to format would be:
* ftpm_tee_tpm_op_recv() - retrieve fTPM response. * @chip: the tpm_chip description as specified in driver/char/tpm/tpm.h. * @buf: the buffer to store data. * @count: the number of bytes to read.
Since it is both a callback to an interface defined elsewhere and a static function and it does not document anything useful, I would just remove this comment. I'd do it for all callbacks that are part of tpm_call_ops.
