Subject: [PATCH 1/3] dma-buf: add missing EXPORT_SYMBOL_GPL() for dma heaps
Date: Tue, 18 Aug 2020 17:04:13 +0900 [thread overview]
Message-ID: <20200818080415.7531-2-hyesoo.yu@samsung.com> (raw)
In-Reply-To: <20200818080415.7531-1-hyesoo.yu@samsung.com>
The interface of dma heap is used from kernel module to
register dma heaps, otherwize we will get compile error.
