Jarkko Sakkinen 8f7f35e5aa tpm: Enable hwrng only for Pluton on AMD CPUs ... The vendor check introduced by commit 554b841d47 ("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 on Lenovo Legion Y540 laptop. 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.
