Subject: [PATCH v5 11/13] mmc: sdhci-tegra: use sdhci_pltfm_init for private allocation
Date: Tue, 16 Feb 2016 21:08:29 +0800	[thread overview]
Message-ID: <1455628111-5583-12-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1455628111-5583-1-git-send-email-jszhang@marvell.com>

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-tegra
to this allocation.
