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/) // <smpl> @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 = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/tty/serial/altera_jtaguart.c | 2 +- drivers/tty/serial/altera_uart.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/tty/serial/altera_jtaguart.c b/drivers/tty/serial/altera_jtaguart.c index 32df2a0..e409d7d 100644 --- a/drivers/tty/serial/altera_jtaguart.c +++ b/drivers/tty/serial/altera_jtaguart.c @@ -280,7 +280,7 @@ static int altera_jtaguart_verify_port(struct uart_port *port, /* * Define the basic serial functions we support. */ -static struct uart_ops altera_jtaguart_ops = { +static const struct uart_ops altera_jtaguart_ops = { .tx_empty = altera_jtaguart_tx_empty, .get_mctrl = altera_jtaguart_get_mctrl, .set_mctrl = altera_jtaguart_set_mctrl, diff --git a/drivers/tty/serial/altera_uart.c b/drivers/tty/serial/altera_uart.c index 61b607f..820a742 100644 --- a/drivers/tty/serial/altera_uart.c +++ b/drivers/tty/serial/altera_uart.c @@ -404,7 +404,7 @@ static void altera_uart_poll_put_char(struct uart_port *port, unsigned char c) /* * Define the basic serial functions we support. */ -static struct uart_ops altera_uart_ops = { +static const struct uart_ops altera_uart_ops = { .tx_empty = altera_uart_tx_empty, .get_mctrl = altera_uart_get_mctrl, .set_mctrl = altera_uart_set_mctrl, -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
