Re: [PATCH v3 06/14] tpm-sysbus: add plug handler for TPM on SysBus

[Joelle van Dyne]

I was debating what to add. I couldn't find a project-wide template
for what the header should be and I couldn't copy/paste from where I
copied the code from (virt.c) because it names a specific author that
I'm not sure wrote this code... Any advice?
