[PATCH v2] i2c: return probe deferred status on dev_pm_domain_attach

From: Kieran Bingham
Date: Mon Oct 12 2015 - 15:49:24 EST


A change of return status was introduced in commit 3fffd1283927
("i2c: allow specifying separate wakeup interrupt in device tree")

The commit prevents the defer status being passed up the call stack
appropriately when dev_pm_domain_attach returns -EPROBE_DEFER.

Catch the PROBE_DEFER and clear up the IRQ wakeup status

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

V2:
Fall through the error path before returning -EPROBE_DEFER
