kernel errors only showing on reboot - nouveau & tpm_crb

Every time that I reboot this shows up in my daily logwatch -

--8<---------------cut here---------------start------------->8---
 WARNING:  Kernel Errors Present
    intel-lpss: probe of 0000:00:1e.0 failed with error -22 ...:  2 Time(s)
    nouveau: probe of 0000:01:00.0 failed with error -12 ...:  2 Time(s)
    tpm_crb: probe of MSFT0101:00 failed with error -16 ...:  2 Time(s)
--8<---------------cut here---------------end--------------->8---

According to dmidecode my CPU is -'Version: Intel(R) Core(TM) i5-7500
CPU @ 3.40GHz' so I would guess that I do need 'intel-lpss' but not need
anything 'nouveau*'? Is that correct please?

But what about 'tpm_crb'? I've done 'lsmod | grep tpm' and 'dmesg | grep
-w tpm' and 'dmesg | grep -i tpm' but nothing is showing up, so I'm
guessing that I don't need 'tpm_crb' either, am I correct? I've been
using [fn:1] as a guide for me to investigate TPM.

I'm sorry if it seems like I'm asking very basic questions, but I just
want to be sure that I'm not going to ask my machine to commit suicide
by me actually removing them!
