From cc2aaabfd6d6335e2156781ca67715b4de17f993 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 10 Oct 2015 16:00:54 -0400 Subject: tty: Remove tty_port::close_wait With the removal of tty_wait_until_sent_from_close(), tty drivers no longer wait during open for parallel closes to complete (instead, the tty core waits before calling the driver open() method). Thus, the close_wait waitqueue is no longer used for waiting. Remove struct tty_port::close_wait.
