Set the firmware framebuffer's parent device, which usually is the graphics hardware's physical device. Integrates the framebuffer in the Linux device hierarchy and lets Linux handle dependencies among devices. For example, the graphics hardware won't be suspended while the firmware device is still active. v4: * fix build for CONFIG_SYSFB_SIMPLEFB=n, again v3: * fix build for CONFIG_SYSFB_SIMPLEFB=n (Sui) * test result of screen_info_pci_dev() for errors (Sui) v2: * detect parent device in sysfb_parent_dev() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-4-tzimmermann@suse.de
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.
