[PATCH] pinctrl: exynos: remove duplicate calls in irq handler

[perr]

Because chained_irq_enter() has already called chip->irq_mask() and
chip->irq_ack(), also chained_irq_exit() will call chip->irq_unmask(),
so it's not necessary to call chip->irq_*() here.

Looks correct so for the patch itself:
Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>

However, your name "Perr" confuses me a little bit. For the
Signed-off-by statement, as mentioned in
Documentation/SubmittingPatches, a real name is required. The name
should match the author.

Would you be so kind as to use a full, real name? Unless Perr is your
full, real name... then sorry for the trouble.

Best regards,
Krzysztof
