From 74cedd30522819d87131715ca0e7d041748b2721 Mon Sep 17 00:00:00 2001 From: Kieran Bingham Date: Mon, 12 Oct 2015 21:54:43 +0100 Subject: [PATCH] i2c: return probe deferred status on dev_pm_domain_attach 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.
