Subject: [PATCH v2 04/12] ASoC: qdsp6: q6adm: use of_platform_populate/depopulate()
Date:   Tue, 26 Jun 2018 10:20:08 +0100
Message-Id: <20180626092016.9296-5-srinivas.kandagatla@linaro.org>
In-Reply-To: <20180626092016.9296-1-srinivas.kandagatla@linaro.org>
References: <20180626092016.9296-1-srinivas.kandagatla@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Now that the child nodes have there own compatible strings,
Use of_platform_populate/depopulate() instead of less common
of_platform_device_create()/destroy().
