We call __save_depot_stack() unconditionally so the stack depot must always be initialized or else we'll oops on platforms without runtime pm support. Presumably we've not seen this in CI due to stack_depot_init() already getting called via drm_mm_init()+CONFIG_DRM_DEBUG_MM.

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.
