+Subject: [PATCH] usb: phy: move some error messages to debug

-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.
+the PHY layer is supposed to be optional,
+considering some PHY have no control bus
+for SW to poke around.
 
-Drop the severity of this message to pr_debug.
+After commit 1ae5799 (usb: hcd: Initialize
+USB phy if needed) any HCD which didn't provide
+a PHY driver would emit annoying error messages.
 
-Signed-off-by: Josh Boyer <jwboyer@fedoraproject.org>
+In this patch we're decreasing those messages
+to debugging only and we also add a PHY prefix
+so we know where they're coming from.
