[PATCH v5 06/19] mlx5: Replace PCI pool old API

From: Romain Perier <hidden>
Date: 2017-03-08 16:25:56
Also in: linux-rdma, linux-scsi, lkml
Subsystem: mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers: Leon Romanovsky, Saeed Mahameed, Tariq Toukan, Mark Bloch, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.
