commit992bdddaabupstream. Struct bd6107_platform_data refers to a platform device within the Linux device hierarchy. The test in bd6107_backlight_check_fb() compares it against the fbdev device in struct fb_info.dev, which is different. Fix the test by comparing to struct fb_info.device. Fixes a bug in the backlight driver and prepares fbdev for making struct fb_info.dev optional. v2: * move renames into separate patch (Javier, Sam, Michael) Fixes:67b43e5904("backlight: Add ROHM BD6107 backlight driver") Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Cc: Lee Jones <lee@kernel.org> Cc: Daniel Thompson <daniel.thompson@linaro.org> Cc: Jingoo Han <jingoohan1@gmail.com> Cc: dri-devel@lists.freedesktop.org Cc: <stable@vger.kernel.org> # v3.12+ Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230613110953.24176-2-tzimmermann@suse.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.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.
