Subject: i2c: fix wakeup irq parsing

From: Grygorii Strashko <[email protected]>

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")
