Subject: [PATCH v2 08/17] rpmsg: Indirection table for rpmsg_endpoint operations
Date: Thu,  1 Sep 2016 15:28:00 -0700	[thread overview]
Message-ID: <1472768889-3906-9-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1472768889-3906-1-git-send-email-bjorn.andersson@linaro.org>

Add indirection table for rpmsg_endpoint related operations and move
virtio implementation behind this, this finishes of the decoupling of
the virtio implementation from the public API.

Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
---

Per Loic's comment I did consider adding parameter validation to the exposed
functions in this patch, but as the previous implementation did not gracefully
handle bad input parameters I decided to defer this until after this series has
been merged.

Changes since v1:
- Split indirection table into device and endpoint ops
- Moved ops pointer to the public structs to reduce code clutter
- Kerneldoc for rpmsg_endpoint_ops
