Subject: [PATCH] usb: phy: move some error messages to debug
Date: Mon, 27 Jan 2014 09:27:46 -0600

the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.

After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.

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.
