From 6f1a2aa411d03f72f7182f6694fdcc21d569e782 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 7 Apr 2021 11:52:01 +0200 Subject: [PATCH] tty: actually undefine superseded ASYNC flags [ Upstream commit d09845e98a05850a8094ea8fd6dd09a8e6824fff ] Some kernel-internal ASYNC flags have been superseded by tty-port flags and should no longer be used by kernel drivers. Fix the misspelled "__KERNEL__" compile guards which failed their sole purpose to break out-of-tree drivers that have not yet been updated.
