    Subject[PATCH] fix cu3088 group write
    Hi Linus,

    The current cu3088 ccwgroup write code overwrite the last char of the
    given arguments. This patch fixes the problem :

    memcpy is not an option since the string will be used with strncmp with
    a length > BUS_ID_SIZE.
    Please apply.
