Subject: [patch v3 3/3] tty: undo export of tty_open_by_driver
Date: Thu, 20 Jul 2017 08:22:38 +0100 [thread overview]
Message-ID: <20170720072926.362841626@gmail.com> (raw)
In-Reply-To: 20170720072235.186761910@gmail.com
[-- Attachment #1: 21_undo_export_of_tty_open_by_driver --]
[-- Type: text/plain, Size: 1801 bytes --]
Since we have tty_kopen, we no longer need to export tty_open_by_driver.
This patch makes this function static.
