I looked at drivers/mmc/core/sd_ops.c and cmd.arg seems to be cpu endian. The new function assumes that the cpu is little endian and manually converts it to little endian. This is an endian bug. I think my fix is correct or something similar. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
