Subject: [PATCH 2/3] mmc: sdhci-pltfm: dt device does not pass parent to sdhci_alloc_host
Date: Sun,  3 Jul 2011 16:30:50 +0800	[thread overview]
Message-ID: <1309681851-23052-3-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1309681851-23052-1-git-send-email-shawn.guo@linaro.org>

Neither platform based nor dt based device needs to pass the parent
to sdhci_alloc_host.  There is no difference between platform and dt
on this point.

The patch makes the change to pass device itself than its parent to
sdhci_alloc_host for dt case too.  Otherwise the probe function of
sdhci based drivers which is shared between platform and dt will
fail on dt case.
