Use drm_panel_get_modes() to access modes. This has a nice side effect to simplify the code. drm_panel_get_modes() may return a negative value if for example panel is NULL. This is a small change compared to before, but really what we want. v2: - Add more info to changelog (Stefan) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Stefan Agner <stefan@agner.ch> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Cc: Alison Wang <alison.wang@nxp.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190804201637.1240-6-sam@ravnborg.org
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.
