Loading a NuBus driver module on a non-NuBus machine triggers the
BUG_ON(!drv->bus->p) in driver_register(), because bus_register() was
not called, because it is conditional on MACH_IS_MAC.
Fix the crash by calling bus_register() unconditionally. Call it from
a postcore_initcall(), like other busses do.
Hence, the bus type is available for device_register(), which happens
in a subsys initcall, and for driver_register(), which happens in a
device or module initcall.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
