From 174e6fe01e7881caaa350b5e98e4c6189b6cb593 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Sat, 19 Sep 2009 13:13:13 -0700 Subject: [PATCH] cyclades: switch to tty_port_hangup Do not duplicate common tty_port_hangup code. Use it instead. Also do not unset ASYNC_NORMAL_ACTIVE and wake up from the tty_hangup() caller. It makes no sense since we don't check that flag in sleepers. tty_port_hangup() performed later will do the right job.
