+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.

Small changes, the "upstream" doesn't look to be maintained anymore, so if we get any more breaks it might be time to remove this recipe.
