Shin'ichiro Kawasaki 511b3b644e nvmet: pci-epf: move DMA initialization to EPC init callback
For DMA initialization to work across all EPC drivers, the DMA
initialization has to be done in the .init() callback.

This is because not all EPC drivers will have a refclock (which is often
needed to access registers of a DMA controller embedded in a PCIe
controller) at the time the .bind() callback is called.

However, all EPC drivers are guaranteed to have a refclock by the time
the .init() callback is called.

Thus, move the DMA initialization to the .init() callback.

This change was already done for other EPF drivers in
commit 60bd3e039a ("PCI: endpoint: pci-epf-{mhi/test}: Move DMA
initialization to EPC init callback").

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
