I tried grepping for calls to "phy_connect" across the drivers present in
drivers/net. Most of them simply return -ENODEV on failure. The ones
which add prints indicating failure, don't use debug(). For this reason,
I believe that the drivers which don't have any prints in case of
failure might be relying on the printf() within phy_connect() to indicate
failure. Therefore, if the printf() is being changed to debug() in
phy_connect(), maybe all the drivers which currently return -ENODEV,
should have a print added to them as a part of this patch.
