Date: Thu, 2 Jul 2015 17:13:47 +0200 From: Bartosz Tomeczko <bartosz.tomeczko@...il.com> To: Johan Hovold <johan@...nel.org> Cc: linux-kernel@...r.kernel.org, trivial@...nel.org Subject: [TRIVIAL PATCH] usb/serial.h: Increase max number of serial ports per USB-serial device Hello, I am using MOXA USB-to-serial converter with 16 serial ports. This device is namely a MOXA UPort 1650-16. This device works as a simple usb-serial adapter and therefore its driver uses include/linux/usb/serial.h file. In this very file however maximal number of serial ports served by the driver is eight (MAX_NUM_PORTS). I would like to propose a trivial patch which would allow MOXA users to use all ports of the device instead of just having eight of them usable (as it is right now). Trivial change which might be applied on the top of (4da3064d1775810f10f7ddc1c34c3f1ff502a654) is as follows: diff --git a/include/linux/usb/serial.h b/include/linux/usb/serial.h index 704a1ab..b7af736 100644 --- a/include/linux/usb/serial.h +++ b/include/linux/usb/serial.h @@ -20,7 +20,7 @@ #include <linux/kfifo.h> /* The maximum number of ports one device can grab at once */ -#define MAX_NUM_PORTS 8 +#define MAX_NUM_PORTS 16 /* parity check flag */ #define RELEVANT_IFLAG(iflag) (iflag & (IGNBRK|BRKINT|IGNPAR|PARMRK|INPCK)) Best regards Bartosz Tomeczko -- 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/
