Subject: [RFC/PATCH 2/4] PCI: Export PCI ACS and DMA searching functions to modules
Date: Fri, 17 May 2019 11:47:35 -0700 [thread overview]
Message-ID: <1558118857-16912-3-git-send-email-isaacm@codeaurora.org> (raw)
In-Reply-To: <1558118857-16912-1-git-send-email-isaacm@codeaurora.org>
IOMMU drivers that can be compiled as modules may
want to use pci_for_each_dma_alias() and pci_request_acs(),
so export those functions.
Signed-off-by: Isaac J. Manjarres <isaacm@codeaurora.org>
