From b300fb26c59a749bf49559932fa8a85eb916b5a7 Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Tue, 17 Jan 2023 11:03:52 +0200 Subject: tty: Convert ->carrier_raised() and callchains to bool MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return boolean from ->carrier_raised() instead of 0 and 1. Make the return type change also to tty_port_carrier_raised() that makes the ->carrier_raised() call (+ cd variable in moxa into which its return value is stored). Also cleans up a few unnecessary constructs related to this change: return xx ? 1 : 0; -> return xx; if (xx) return 1; return 0; -> return xx; Reviewed-by: Jiri Slaby Acked-by: Ulf Hansson # For MMC Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20230117090358.4796-7-ilpo.jarvinen@linux.intel.com Signed-off-by: Greg Kroah-Hartman --- include/linux/tty_port.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'include/linux') diff --git a/include/linux/tty_port.h b/include/linux/tty_port.h index fa3c3bdaa234..cf098459cb01 100644 --- a/include/linux/tty_port.h +++ b/include/linux/tty_port.h @@ -15,7 +15,7 @@ struct tty_struct; /** * struct tty_port_operations -- operations on tty_port - * @carrier_raised: return 1 if the carrier is raised on @port + * @carrier_raised: return true if the carrier is raised on @port * @dtr_rts: raise the DTR line if @raise is nonzero, otherwise lower DTR * @shutdown: called when the last close completes or a hangup finishes IFF the * port was initialized.
