Subject: [PATCH 06/11] mmc: sdhci-of-esdhc: use sdhci_pltfm_init for private allocation
Date: Tue, 5 Jan 2016 18:51:34 +0800	[thread overview]
Message-ID: <1451991099-4946-7-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1451991099-4946-1-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 the
sdhci-of-esdhc driver to this allocation.
