Subject: [PATCH 3/8] of: dma: Make of_dma_deconfigure() public
Date: Tue, 9 Aug 2016 04:19:05 +0530 [thread overview]
Message-ID: <1470696550-3416-4-git-send-email-sricharan@codeaurora.org> (raw)
In-Reply-To: <1470696550-3416-1-git-send-email-sricharan@codeaurora.org>
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
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.
Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
