Subject: [PATCH 4.3 081/200] i2c: fix wakeup irq parsing

4.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Grygorii Strashko <grygorii.strashko@...com>

commit c18fba23061f16dde128e10d4869ba4e88e0e81a upstream.

This patch fixes obvious copy-past error in wake up irq parsing
code which leads to the fact that dev_pm_set_wake_irq() will
be called with wrong IRQ number when "wakeup" IRQ is not
defined in DT.

Fixes: 3fffd1283927 ("i2c: allow specifying separate wakeup interrupt in device tree")
