From mboxrd@z Thu Jan 1 00:00:00 1970 From: sricharan@codeaurora.org (Sricharan R) Date: Mon, 23 Jan 2017 21:48:06 +0530 Subject: [PATCH V7 04/11] of: dma: Make of_dma_deconfigure() public In-Reply-To: <1485188293-20263-1-git-send-email-sricharan@codeaurora.org> References: <1485188293-20263-1-git-send-email-sricharan@codeaurora.org> Message-ID: <1485188293-20263-5-git-send-email-sricharan@codeaurora.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Laurent Pinchart As part of moving DMA initializing to probe time the of_dma_deconfigure() function will need to be called from different source files. Make it public and move it to drivers/of/device.c where the of_dma_configure() function is.
