Hello Martin Sperl,
The patch bdc5f3009580: "serial: bcm2835: add driver for
bcm2835-aux-uart" from Jan 17, 2016, leads to the following static
checker warning:
drivers/tty/serial/8250/8250_bcm2835aux.c:63 bcm2835aux_serial_probe()
warn: unsigned 'data->uart.port.irq' is never less than zero.
drivers/tty/serial/8250/8250_bcm2835aux.c
60
61 /* get the interrupt */
62 data->uart.port.irq = platform_get_irq(pdev, 0);
63 if (data->uart.port.irq < 0) {
^^^^^^^^^^^^^^^^^^^^^^^
signedness bug.
64 dev_err(&pdev->dev, "irq not found - %i",
65 data->uart.port.irq);
66 return data->uart.port.irq;
67 }
68
regards,
dan carpenter
