We already have it in v3d_dev->drm.dev with zero additional pointer chasing. Personally I don't like duplicated pointers like this because: - reviewers need to check whether the pointer is for the same or different objects if there's multiple - compilers have an easier time too To avoid having to pull in some big headers I implemented the casting function as a macro instead of a static inline. Typechecking thanks to container_of still assured. But also a bit a bikeshed, so feel free to ignore. v2: More parens for v3d_to_pdev macro (checkpatch) Acked-by: Eric Anholt <eric@anholt.net> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/msgid/20200415074034.175360-11-daniel.vetter@ffwll.ch
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.
