    Subject[PATCH 3/7] Char: cyclades, fix unused variable
    Date
    drivers/tty/cyclades.c:1454:2: warning: Value stored to 'channel' is never read
    channel = info->line - card->first_line;
    ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Fix it by moving it to the appropriate debug section where it is used.
