It's not clear to me what this pr_err() is trying to indicate other
than *something* failed. Can someone provide some more background on
this message?

process_buffer_measurement() is currently used to measure
"kexec command line", "keys", and "blacklist-hash". If there was any error in the measurement, this pr_err() will indicate which of the above measurement failed and the related error code.

Please let me know if you need more info on this one.

Since a pr_xyz() call was already present, I just wanted to change the log level to keep the code change to the minimum. But if audit log is the right approach for this case, I'll update.
