Subject: [PATCH v1 1/1] PCI/EDR: Change ACPI event message log level

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>

Currently we have pci_info() message in the beginning of
edr_handle_event() function, which will be printing
notification details every-time firmware sends ACPI SYSTEM
level events. This will pollute the dmesg logs for systems
that has lot for ACPI system level notifications. So change
the log-level to pci_dbg, and add a new info log for EDR
events.
