From 0734e79c0552f944cee8bf4f12fd849eae235554 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Tue, 16 Feb 2016 21:08:29 +0800 Subject: [PATCH] mmc: sdhci-tegra: use sdhci_pltfm_init for private allocation 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.
