From d010e5769a5ab2ae8d2bcb36e77b98172c24d80c Mon Sep 17 00:00:00 2001 From: Lan Tianyu <tianyu.lan@intel.com> Date: Tue, 30 Jul 2013 10:32:30 +0800 Subject: [PATCH] PCI / ACPI: Use dev_dbg() instead of dev_info() in acpi_pci_set_power_state() acpi_pci_set_power_state() uses dev_info() to print diagnostic messages regarding ACPI power state changes of devices, but that results in too much not really interesting output into the kernel log in some cases. For this reason, change it to use dev_dbg() instead and prevent kernel log from being spammed.
