| |
When booting on an ACPI enabled system that does not provide the Platform Communications Channel Table (PCCT), the pcc mailbox driver prints -
[ 0.484261] PCCT header not found.
during probe before returning -ENODEV.
This message clutters the bootlog and doesn't provide any useful information. Drop this message.
