Subject: [PATCH v3 10/10] mfd: mfd-core: Move pdev->mfd_cell creation back into mfd_add_device()
Date:   Thu, 24 Oct 2019 17:38:32 +0100
Message-Id: <20191024163832.31326-11-lee.jones@linaro.org>
In-Reply-To: <20191024163832.31326-1-lee.jones@linaro.org>
References: <20191024163832.31326-1-lee.jones@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Most of the complexity of mfd_platform_add_cell() has been removed. The
only functionality left duplicates cell memory into the child's platform
device. Since it's only a few lines, moving it to the main thread and
removing the superfluous function makes sense.
