From: Raghuveer Murthy <[email protected]> commit bf56f0a6668cd (2.6.37-rc1), from Nishanth Menon attempted to fix card detection for PandaBoard, unfortunately, the fix missed to initialize .gpio_cd member of omap2_hsmmc_info. This results in a default value of '0', which is a valid GPIO line. On PandaBoard, the side effect of this is that GPIO line 0 controls the powering TFP410 DVI chip, and without the fix DVI chip is inadvertently powered.
