From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Shunyong Yang To: CC: , , Shunyong Yang , Joey Zheng Subject: [PATCH] PCI: Unify pci and normal dma direction definition Date: Fri, 13 Jul 2018 14:37:20 +0800 Message-ID: <1531463840-34651-1-git-send-email-shunyong.yang@hxt-semitech.com> MIME-Version: 1.0 Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org List-ID: Current DMA direction definitions in pci-dma-compat.h and dma-direction.h are mirrored in value. Unify them to enhance readability and avoid possible inconsistency.
