Date: Mon, 16 Feb 2015 15:57:58 +0800 From: Peter Hung <hpeter@...il.com> To: johan@...nel.org Cc: gregkh@...uxfoundation.org, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, tom_tsai@...tek.com.tw, peter_hong@...tek.com.tw, Peter Hung <hpeter+linux_kernel@...il.com> Subject: [PATCH V6 06/10] USB: f81232: clarify f81232_ioctl and fix We extract TIOCGSERIAL section in f81232_ioctl() to f81232_get_serial_info() to make it clarify. Also we fix device type from 16654 to 16550A, and set it's baud_base to 115200 (1.8432MHz/16) Signed-off-by: Peter Hung <hpeter+linux_kernel@...il.com> --- drivers/usb/serial/f81232.c | 30 +++++++++++++++++++----------- 1 file changed, 19 insertions(+), 11 deletions(-) diff --git a/drivers/usb/serial/f81232.c b/drivers/usb/serial/f81232.c index e1cdf42..e70ec62 100644 --- a/drivers/usb/serial/f81232.c +++ b/drivers/usb/serial/f81232.c @@ -516,24 +516,32 @@ static int f81232_carrier_raised(struct usb_serial_port *port) return 0; } +static int f81232_get_serial_info(struct usb_serial_port *port, + unsigned long arg) +{ + struct serial_struct ser; + + memset(&ser, 0, sizeof(ser)); + + ser.type = PORT_16550A; + ser.line = port->minor; + ser.port = port->port_number; + ser.baud_base = 115200; + + if (copy_to_user((void __user *)arg, &ser, sizeof(ser))) + return -EFAULT; + + return 0; +} + static int f81232_ioctl(struct tty_struct *tty, unsigned int cmd, unsigned long arg) { - struct serial_struct ser; struct usb_serial_port *port = tty->driver_data; switch (cmd) { case TIOCGSERIAL: - memset(&ser, 0, sizeof ser); - ser.type = PORT_16654; - ser.line = port->minor; - ser.port = port->port_number; - ser.baud_base = 460800; - - if (copy_to_user((void __user *)arg, &ser, sizeof ser)) - return -EFAULT; - - return 0; + return f81232_get_serial_info(port, arg); default: break; } -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
