Subject: [PATCH] tty: drop put_tty_driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 9f90a4ddef4e4d3aa4229f6b117d4e57231457b3
References: jsc#PED-531
Patch-mainline: v5.15-rc1
put_tty_driver() is an alias for tty_driver_kref_put(). There is no need
for two exported identical functions, therefore switch all users of
old put_tty_driver() to new tty_driver_kref_put() and remove the former
for good.
