Message-ID: <20200718094328.GA2102@blackclown>
Date: Sat, 18 Jul 2020 15:13:28 +0530
From: Suraj Upadhyay <usuraj35@...il.com>
To: oliver@...kum.org, aliakc@....de, lenehan@...bble.org,
jejb@...ux.ibm.com, don.brace@...rosemi.com

Subject: [PATCH] scsi: hpsa and dc395x: Remove pci_dma_compat wrapper APIs.
The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs, instead use dma-mapping.h
APIs directly.
The patch has been generated with the coccinelle script below
and compile-tested.
