Subject: [PATCH RESEND 2/5] net: mdio-gpio: warn about missing bus alias id
Date: Thu,  8 May 2014 10:09:21 +0200	[thread overview]
Message-ID: <1399536564-7626-3-git-send-email-jhovold@gmail.com> (raw)
In-Reply-To: <1399536564-7626-1-git-send-email-jhovold@gmail.com>

Use a sane default bus id (rather than -ENODEV) and print a warning when
the bus alias id is missing.
