The vendor check introduced by commit 554b841d4703 ("tpm: Disable RNG for all AMD fTPMs") doesn't work properly on a number of Intel fTPMs. On the reported systems the TPM doesn't reply at bootup and returns back the command code. This makes the TPM fail probe.
Since only Microsoft Pluton is the only known combination of AMD CPU and fTPM from other vendor, disable hwrng otherwise. In order to make sysadmin aware of this, print also info message to the klog.

Mario’s patch also had the three reporters below listed:
Reported-by: Patrick Steinhardt ps@pks.im Reported-by: Ronan Pigott ronan@rjp.ie Reported-by: Raymond Jay Golo rjgolo@gmail.com
The problem here is that checkpatch throws three warnings:
WARNING: Reported-by: should be immediately followed by Closes: with a URL to the report #19: Reported-by: Patrick Steinhardt ps@pks.im Reported-by: Ronan Pigott ronan@rjp.ie
WARNING: Reported-by: should be immediately followed by Closes: with a URL to the report #20: Reported-by: Ronan Pigott ronan@rjp.ie Reported-by: Raymond Jay Golo rjgolo@gmail.com

FWIW I observed the same checkpatch warning when I submitted my version of the patch. I figured it's better to ignore the warning and attribute everyone who reported the issue affected them.
If nothing else it gives more people to pull in and check any future fixes if there is a regression caused by this patch that forces it to be reverted.
Since bugzilla is not part of the documented process afaik, I used this field as the guideline:
Reported: 2023-08-17 20:59 UTC by Todd Brandt
How otherwise I should interpret kernel bugzilla?
In any case new version is still needed as the commit message must contain a mention of "Lenovo Legion Y540" as the stimulus for doing this code change in the first place.
BR, Jarkko
