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 --- diff --git a/drivers/tty/serial/bcm63xx_uart.c b/drivers/tty/serial/bcm63xx_uart.c index 5108fab953aa..583c9a0c7ecc 100644 --- a/drivers/tty/serial/bcm63xx_uart.c +++ b/drivers/tty/serial/bcm63xx_uart.c @@ -631,7 +631,7 @@ static int bcm_uart_verify_port(struct uart_port *port, } /* serial core callbacks */ -static struct uart_ops bcm_uart_ops = { +static const struct uart_ops bcm_uart_ops = { .tx_empty = bcm_uart_tx_empty, .get_mctrl = bcm_uart_get_mctrl, .set_mctrl = bcm_uart_set_mctrl,
