The Qualcomm Command DB driver seems to have been indirectly enabled by
the Qualcomm DRM driver and up until the introduction of '778279f4f5e4
("soc: qcom: cmd-db: allow loading as a module")' this resulted in the
driver "always" being builtin on arm64. But with the introduction of
said change it, and all other RPMH related drivers, becomes =m.
The immediate result is that the uart driver fails to probe, which
depending on userspace's dependency on the presence of /dev/console
might be fatal. For systems getting past this the default timeout of 0
seconds for probe deferral of many subsystems causes the system to be
completely useless.
So, make Command DB builtin.

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.
