From 6af9a43d58f2ec455b752fb9534cf05c7e855dbe Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 24 Jun 2009 18:35:05 +0100 Subject: tty: fix tty_port_block_til_ready waiting Since commit 3e3b5c087799e536871c8261b05bc28e4783c8da ("tty: use prepare/finish_wait"), tty_port_block_til_ready() is using prepare_to_wait()/finish_wait(). Those functions require that the wait_queue_t be initialised with .func=autoremove_wake_function, via DEFINE_WAIT(). But the conversion from DECLARE_WAITQUEUE() to DEFINE_WAIT() was not made, so this code will oops in finish_wait().
