Subject: [PATCH 3/4] RDMA/qib: Remove pci-dma-compat wrapper APIs
Date: Sun, 9 Aug 2020 13:02:16 +0530 [thread overview]
Message-ID: <2221f49fba32a2fbeab6dafbb93ec68498186c37.1596957073.git.usuraj35@gmail.com> (raw)
In-Reply-To: <cover.1596957073.git.usuraj35@gmail.com>
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.
