From f098a0ae62f7eb7cef27bd83245d798bd45b428d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 19:51:36 +0200 Subject: [PATCH] tty: xuartps: 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 Signed-off-by: Greg Kroah-Hartman --- drivers/tty/serial/xilinx_uartps.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/tty/serial/xilinx_uartps.c b/drivers/tty/serial/xilinx_uartps.c index 9ca1a4d1b66a..11a2b36e14bb 100644 --- a/drivers/tty/serial/xilinx_uartps.c +++ b/drivers/tty/serial/xilinx_uartps.c @@ -993,7 +993,7 @@ static void cdns_uart_pm(struct uart_port *port, unsigned int state, } } -static struct uart_ops cdns_uart_ops = { +static const struct uart_ops cdns_uart_ops = { .set_mctrl = cdns_uart_set_mctrl, .get_mctrl = cdns_uart_get_mctrl, .start_tx = cdns_uart_start_tx, -- 2.20.1
