gpio/omap: fix wakeup_en register update in _set_gpio_wakeup()
There are two ways through which wakeup_en register can be programmed using gpiolib APIs as shown below. It is seen that in the second case in _set_gpio_wakeup(), even though bank->suspend_wakeup is updated correctly, its value is not programmed in wakeup_en register. Fix this. irq_set_type()->gpio_irq_type()->_set_gpio_triggering()->set_gpio_trigger() irq_set_wake()->gpio_wake_enable()->_set_gpio_wakeup() Signed-off-by: Tarun Kanti DebBarma <tarun.kanti@ti.com> Reviewed-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
