From 3770ee8f95a2aa2da66db460a10898e96eee1b13 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 17 Oct 2013 15:19:46 +0800 Subject: [PATCH] mmc: sdhci-esdhc-imx: pdev->id_entry should be immutable As a good practice, device driver should not modify pdev->id_entry but keep it immutable. Let's assign of_device_id.data with imx_esdhc_type constants directly, so that we do not have to manipulate pdev->id_entry in .probe(). As the result, sdhci-esdhc-imx53 and sdhci-usdhc-imx6q can be removed from platform_device_id table now, since they will only probe from device tree.
