Subject: i2c: fix wakeup irq parsing
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c18fba23061f16dde128e10d4869ba4e88e0e81a;p=openwrt%2Fstaging%2Fblogic.git

i2c: fix wakeup irq parsing

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")
