[PATCH RESEND] mailbox: pcc: Drop uninformative output during boot

From: Punit Agrawal
Date: Tue Aug 01 2017 - 08:44:23 EST


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.
