From 80f13c7cb8c2b83b6b38a953ad69b91cab9dc614 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Sat, 25 Jan 2014 10:00:41 -0500 Subject: [PATCH] usb: phy: Quiet unable to find transceiver message commit 1ae5799ef6317 ("usb: hcd: Initialize USB phy if needed") allows the USB layer to initialize external PHYs if needed. However, a PHY is not needed in all cases. The usb_get_phy_device function will print an error message, "unable to find transceiver" but everything still functions normally. Drop the severity of this message to pr_debug.
