The patch titled
tty_io.c balance tty_ldisc_ref()
has been removed from the -mm tree. Its filename was
tty_ioc-balance-tty_ldisc_ref.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: tty_io.c balance tty_ldisc_ref()
From: Dan Carpenter <error27@xxxxxxxxx>
tty_ldisc_deref() should only be called when tty_ldisc_ref() succeeds
otherwise it triggers a BUG(). There's already a function
tty_ldisc_flush() that flushes properly.
