From 10f1c1352cb9a0a52a60a681dc6b4822416937ac Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Tue, 16 Feb 2016 21:08:25 +0800 Subject: [PATCH] mmc: sdhci-of-at91: 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 the sdhci-of-at91 driver to this allocation.
