Subject: [PATCH] TPM: Print messages if measuraments fail as debug instead of
|
|
error
|
|
|
|
If the calls to EFI services to do TPM measuraments fail, currently error
|
|
messages are printed. But this is not a fatal error and just pollutes the
|
|
output, so instead just print them as debug messages.
|
|

Resolves: rhbz#1761811
