Subject: [PATCH] net: davinci_emac: fix dev_err use at probe
Date: Thu, 26 May 2011 16:37:32 +0200 [thread overview]
Message-ID: <1306420652-30001-1-git-send-email-jhovold@gmail.com> (raw)
Use platform device rather than net device in dev_err calls before net
device has been registered to avoid messages such as
(null): DaVinci EMAC: Failed to get EMAC clock
Also replace remaining printks in probe with dev_{err,warn}.
