From 947d66b68f3c4e7cf8f3f3500807b9d2a0de28ce Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Fri, 11 Nov 2022 16:25:02 +0200 Subject: n_tty: Rename tail to old_tail in n_tty_read() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The local tail variable in n_tty_read() is used for one purpose, it keeps the old tail. Thus, rename it appropriately to improve code readability.
