From 7e6e1312629f9bc7a24871f7f395f2d288a1758f Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 18 Apr 2023 11:38:54 -0500 Subject: [PATCH] Support Linux kernels v5.15+ put_tty_driver was removed and write_room return type has changed. Function tty_driver_kref_put has been around a while, so no need to do a kernel version check.
