+Subject: [PATCH 2/5] PCI/EDR: Log only ACPI_NOTIFY_DISCONNECT_RECOVER events
+
+Previously we logged *all* ACPI SYSTEM-level events, which may include lots
+of non-EDR events. Move the message so we only log those related to EDR.
+
+Link: https://lore.kernel.org/r/01afb4e01efbe455de0c445bef6cf3ffc59340d2.1586996350.git.sathyanarayanan.kuppuswamy@linux.intel.com
+[bhelgaas: drop the pci_dbg() of all events since ACPI can log those
+already]
