The return code gets overridden due to the call to host->pdata->resume()
which always returns 0.

static int omap_hsmmc_resume_cdirq(struct device *dev, int slot)
{
        struct omap_mmc_platform_data *mmc = dev->platform_data;

        enable_irq(mmc->slots[0].card_detect_irq);
        return 0;
}
