Subject: [PATCH v2 11/17] rpmsg: Split off generic tail of create_channel()
Date: Thu, 1 Sep 2016 15:28:03 -0700 [thread overview]
Message-ID: <1472768889-3906-12-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1472768889-3906-1-git-send-email-bjorn.andersson@linaro.org>
The tail of create_channel() is common among all rpmsg backends, so
split it off from the virtio specific part to allow it to be extracted
to the rpmsg core.
