Fenghua Yu 0806a6afe1 dmaengine: idxd: Register dsa_bus_type before registering idxd sub-drivers 
[ Upstream commit 88928addee ]

idxd sub-drivers belong to bus dsa_bus_type. Thus, dsa_bus_type must be
registered in dsa bus init before idxd drivers can be registered.

But the order is wrong when both idxd and idxd_bus are builtin drivers.
In this case, idxd driver is compiled and linked before idxd_bus driver.
Since the initcall order is determined by the link order, idxd sub-drivers
are registered in idxd initcall before dsa_bus_type is registered
in idxd_bus initcall. idxd initcall fails:

[   21.562803] calling  idxd_init_module+0x0/0x110 @ 1
[   21.570761] Driver 'idxd' was unable to register with bus_type 'dsa' because the bus was not initialized.
[   21.586475] initcall idxd_init_module+0x0/0x110 returned -22 after 15717 usecs
[   21.597178] calling  dsa_bus_init+0x0/0x20 @ 1

To fix the issue, compile and link idxd_bus driver before idxd driver
to ensure the right registration order.

README 

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 Restructured Text 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.
