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.
