The symbol hwa742_update_window_async() is exported, but there is no prototype defined for it. That's why gcc complains: drivers-video-fbdev-omap-hwa742.c⚠️no-previous-prototype-for-hwa742_update_window_async Add the prototype, but I wonder if we couldn't drop exporting the symbol instead. Since omapfb_update_window_async() is exported the same way, are there any users outside of the tree? Signed-off-by: Helge Deller <deller@gmx.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.
