  "message": "tty: fix tty_line must not be equal to number of allocated tty pointers in tty driver\n\nI found a bug \"by chance\" in drivers/char/tty_io.c\n\nI mean \"by chance\" because I was just reading the code of the\ntty_find_polling_driver() to make a new tty_find_by_name() function.\n\nIn tty_find_polling_driver() the driver actually test \"tty_line \u003c\u003d\np-\u003enum\" while num refers to the number of struct tty_struct pointers\nallocated for the p-\u003ettys (p is a tty_driver), and tty_line is scanned\nin a tty name, which can be for example ttyS2. Then tty_line equals 2.\nAnd if p-\u003enum is 2, we have only p-\u003ettys[0] and p-\u003ettys[1], but no\np-\u003ettys[2].\n\nThis is actually unharmful, for tty_find_polling_driver() is used only\nin drivers/serial/kgdboc.c, and there\u0027s a test over there to find a\nconsole with a matching index, which will never happen.\n\nThis is still a bug anyway.\n\nSigned-off-by: Nathael Pajani \u003cnathael.pajani@ed3l.fr\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
