The IRQ handler rt5640_irq() runs in interrupt context and can sleep

Fix this by running IRQ handler, rt5640_irq(), in thread context.
Hence replace request_irq() calls with devm_request_threaded_irq().
-		ret = request_irq(rt5640->jd_gpio_irq, rt5640_jd_gpio_irq,
-				  IRQF_TRIGGER_RISING | IRQF_TRIGGER_FALLING,
-				  "rt5640-jd-gpio", rt5640);
+		ret = devm_request_threaded_irq(component->dev,
+				rt5640->jd_gpio_irq,
+				NULL, rt5640_jd_gpio_irq,
+				IRQF_TRIGGER_RISING | IRQF_TRIGGER_FALLING,
+				"rt5640-jd-gpio", rt5640);
This is rt5640_jd_gpio_irq() which just does a queue_delayed_work() not
a cancel.  Why is it being changed?

Will drop this part in v2. Thanks.
