The GPIO trigger parameter is of type unsigned. enum { IRQ_TYPE_NONE = 0x00000000, IRQ_TYPE_EDGE_RISING = 0x00000001, IRQ_TYPE_EDGE_FALLING = 0x00000002, IRQ_TYPE_EDGE_BOTH = (IRQ_TYPE_EDGE_FALLING | IRQ_TYPE_EDGE_RISING), IRQ_TYPE_LEVEL_HIGH = 0x00000004, IRQ_TYPE_LEVEL_LOW = 0x00000008, IRQ_TYPE_LEVEL_MASK = (IRQ_TYPE_LEVEL_LOW | IRQ_TYPE_LEVEL_HIGH), IRQ_TYPE_SENSE_MASK = 0x0000000f,
IRQ_TYPE_PROBE = 0x00000010, ... }; Even though gpio_irq_type(struct irq_data *d, unsigned type) has the right type of parameter, the subsequent called functions set_gpio_triggering() and set_gpio_trigger() wrongly makes it signed integer. Fix this.
