Subject: [PATCH] of: overlay: pr_err from return NOTIFY_OK to overlay apply/remove
Date: Thu, 19 Oct 2017 14:18:27 -0700 [thread overview]
Message-ID: <1508447907-4462-1-git-send-email-frowand.list@gmail.com> (raw)
From: Frank Rowand <frank.rowand-7U/KSKJipcs@public.gmane.org>
A device tree overlay notifier can return NOTIFY_OK, NOTIFY_STOP,
or an embedded errno. overlay_notify() incorrectly reports an
error for NOTIFY_OK.
