Subject: [PATCH] pinctrl: exynos: ack level-triggered interrupts before
 unmasking

A level-triggered interrupt should be acked after the interrupt line
becomes inactive and before it is unmasked, or else another interrupt
will be immediately triggered.  Acking before or after calling the
handler is not enough.
