Jiri Slaby 7f90cfc505 TTY: ldisc, fix open flag handling ... When a concrete ldisc open fails in tty_ldisc_open, we forget to clear TTY_LDISC_OPEN. This causes a false warning on the next ldisc open: WARNING: at drivers/char/tty_ldisc.c:445 tty_ldisc_open+0x26/0x38() Hardware name: System Product Name Modules linked in: ... Pid: 5251, comm: a.out Tainted: G W 2.6.32-5-686 #1 Call Trace: [<c1030321>] ? warn_slowpath_common+0x5e/0x8a [<c1030357>] ? warn_slowpath_null+0xa/0xc [<c119311c>] ? tty_ldisc_open+0x26/0x38 [<c11936c5>] ? tty_set_ldisc+0x218/0x304 ... So clear the bit when failing... Introduced in c65c9bc3ef (tty: rewrite the ldisc locking) back in 2.6.31-rc1.
