2008-07-20tty: Ldisc revampAlan Cox
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.

Coverity CID: 1356 RESOURCE_LEAK I found a very old patch for this that was Acked but did not get applied https://lists.linux-foundation.org/pipermail/kernel-janitors/2006-September/016362.html There looks to be a small leak in isdn_writebuf_stub() in isdn_common.c, when copy_from_user() returns an un-copied data length (length != 0).

2008-05-14hysdn: Remove cli()/sti() calls.Mark Asselstine
The use of cli()/sti() within the do/while was a way to ensure interrupts were only disabled for short periods of time while the bulk of the time interrupts were free to occur. The use of the spin lock has eliminated the need to play with interrupts in this way while still allowing for IO to be protected. The remaining 3 sti() calls seem unneeded now that at no other point in the driver is there a call to cli().
