From 933505e9b41759fb7cb8a1b648553d7c00a8bf1c Mon Sep 17 00:00:00 2001 From: Dmitry Safonov Date: Fri, 13 Dec 2019 00:06:10 +0000 Subject: [PATCH] tty/serial: Migrate arc_uart to use has_sysrq The SUPPORT_SYSRQ ifdeffery is not nice as: - May create misunderstanding about sizeof(struct uart_port) between different objects - Prevents moving functions from serial_core.h - Reduces readability (well, it's ifdeffery - it's hard to follow) In order to remove SUPPORT_SYSRQ, has_sysrq variable has been added. Initialise it in driver's probe and remove ifdeffery.
