From 5d9b9530e36bca7cd8306c5097623692e1134c39 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 19:51:34 +0200 Subject: [PATCH] tty: serial: jsm_tty: constify uart_ops structures Check for uart_ops structures that are only stored in the ops field of a uart_port structure. This field is declared const, so uart_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct uart_ops i@p = { ... }; @ok@ identifier r.i; struct uart_port e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct uart_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct uart_ops i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Gabriel Krisman Bertazi Signed-off-by: Greg Kroah-Hartman --- drivers/tty/serial/jsm/jsm_tty.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/tty/serial/jsm/jsm_tty.c b/drivers/tty/serial/jsm/jsm_tty.c index c5ddfe542451..ec7d8383900f 100644 --- a/drivers/tty/serial/jsm/jsm_tty.c +++ b/drivers/tty/serial/jsm/jsm_tty.c @@ -346,7 +346,7 @@ static void jsm_config_port(struct uart_port *port, int flags) port->type = PORT_JSM; } -static struct uart_ops jsm_ops = { +static const struct uart_ops jsm_ops = { .tx_empty = jsm_tty_tx_empty, .set_mctrl = jsm_tty_set_mctrl, .get_mctrl = jsm_tty_get_mctrl, -- 2.39.2
