From e5b9f4b1dc3e73f8a327b242c783551c4bf15bbd Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Thu, 23 Jul 2020 17:31:27 -0500 Subject: [PATCH] tty: Avoid the use of one-element arrays One-element arrays are being deprecated[1]. Replace the one-element arrays with simple value types 'char reserved_char' and 'compat_int_t reserved'[2], once it seems these are just placeholders for alignment.
