xe_pm_init may encounter failures for various reasons, such as a failure in initializing drmm_mutex, or when dealing with a d3cold-capable device for vram_threshold sysfs creation and setting default threshold. Presently, all these potential failures are disregarded. Move d3cold.lock initialization to xe_pm_init_early and cause driver abort if mutex initialization has failed. For xe_pm_init failures cleanup the driver and return error code -v2 Make mutex init cleaner (Lucas) Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240412181211.1155732-8-himal.prasad.ghimiray@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
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.
