[PATCH 4.19 38/52] RDMA/ulp: Use dev_name instead of ibdev->name

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gunthorpe <jgg@mellanox.com>

[ Upstream commit 6c8541118bd53bc90b6c2473e289e5541de80376 ]

These return the same thing but dev_name is a more conventional use of the
kernel API.
