From cbf4b3867875206aa548a8c6d7c886f3299d619e Mon Sep 17 00:00:00 2001 From: Okash Khawaja Date: Sat, 17 Jun 2017 22:32:55 +0100 Subject: [PATCH] tty: define tty_open_by_driver when CONFIG_TTY is not defined This patch adds definition of tty_open_by_driver when CONFIG_TTY is not defined. This was supposed to have been included in commit 12e84c71b7d4ee38d51377fd494ac748ee4e6912 ("tty: export tty_open_by_driver"). The patch follows convention for other such functions and returns NULL.
