OK, I built a kernel with the two patches applied, and with and without commit
7f3d176f5f7e, and when I run "sudo fwupdtpmevlog" (which normally causes a
panic() when 7f3d176f5f7e is in place) and the results are:

- With 7f3d176f5f7e reverted, no WARNs of any kind
- With 7f3d176f5f7e in place, same, I just get "UEFI TPM log area empty"
