From 5964dadd0371238cbc91b1c2b6b24fd7d83833d8 Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Mon, 3 Dec 2012 02:19:42 +0000 Subject: omap_hsmmc: fix out of bounds array access There are 3 MMC/SD/SDIO controllers in OMAP SoCs, but only 2 structs are defined for devices. This leads to data being written outside of array bounds on systems that use all 3 controllers. Update hsmmc_dev array to the correct size.

If there is any change in control module for any of the ES versions, a new structure needs to be created. In order to remove this dependency, making the register structure generic for all the omap4+ boards.
