Ben Hutchings edd05afa41 fbdev: vt8500lcdfb: Fix dma_free_coherent() cpu_addr parameter Before commit `63a11adace` "fbdev/vt8500lcdfb: Initialize fb_ops with fbdev macros", the virtual address of the screen buffer was stored in the fb_info::screen_base field and not fb_info::screen_buffer. The backport of commit `88b3b99243` ("fbdev: vt8500lcdfb: fix missing dma_free_coherent()") did not take that into account. Change the cpu_addr parameter to dma_free_coherent() accordingly. Fixes: `9c3873cccb` ("fbdev: vt8500lcdfb: fix missing dma_free_coherent()") Signed-off-by: Ben Hutchings <benh@debian.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		History 2026-06-19 13:33:50 +02:00

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.
