Subject: [PATCH 6/8] tty: make tty_set_operations an inline
Date:   Fri, 23 Jul 2021 09:43:15 +0200
Message-Id: <20210723074317.32690-7-jslaby@suse.cz>

Since commit f34d7a5b7010 (tty: The big operations rework) in 2008,
tty_set_operations() is a simple one-line assignment. There is no reason
for this to be an exported function, hence move it to a header and make
an inline from that.
