* tty: rework break handlingAlan Cox2008-07-221-4/+4
| | | | | | | | | Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* tty: Ldisc revampAlan Cox2008-07-201-1/+2
| | | | | | | | | | | | Move the line disciplines towards a conventional ->ops arrangement. For the moment the actual 'tty_ldisc' struct in the tty is kept as part of the tty struct but this can then be changed if it turns out that when it all settles down we want to refcount ldiscs separately to the tty. Pull the ldisc code out of /proc and put it with our ldisc code. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* tty/serial: lay the foundations for the next set of reworksAlan Cox2008-04-301-36/+40
| | | | | | | | | | | | | | | | | | | | | | | | - Stop drivers calling their own flush method indirectly, it obfuscates code and it will change soon anyway - A few more lock_kernel paths temporarily needed in some driver internal waiting code - Remove private put_char method that does a write call for one char - we have that anyway - Most but not yet all of the termios copy under lock fixing (some has other dependencies to follow) - Note a few locking bugs in drivers found in the process - Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to fix the termios locking Signed-off-by: Alan Cox <alan@redhat.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Char: cyclades, fix potential NULL dereferenceJiri Slaby2007-10-231-1/+1
| | | | | | | | | | | | | | | | ztxdone is jumped to even if tty is NULL and tty_wakeup placed after this label doesn't expect NULLed parameter, so this will cause an oops in some situations (why they scheduled a wakeup there before remove bottom half processing patch?). wakeup only in the case when we have non-null tty struct.
