From b5def43a7b3e7e68d6b49a23166f8b886a26bb54 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Thu, 9 Mar 2023 10:09:21 +0200 Subject: [PATCH] serial: Make hw_stopped bool MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Convert hw_stopped in uart_port to bool because its more appropriate type for how it is used. Also convert the local variable in uart_change_line_settings() caching old hw_stopped to bool.
