Subject: [PATCH 0/3] drm: Endianness fixes

	Hi all,

This patch series contains several endianness fixes for the DRM
subsystem.

This has been tested on ARAnyM using a work-in-progress Atari DRM
driver, which supports (a.o.) big-endian RGB565 (more info and related
patches can be found in [1]).

Thanks for your comments!

    https://lore.kernel.org/r/cover.1657294931.git.geert@linux-m68k.org

Geert Uytterhoeven (3):
  drm/fourcc: Add missing big-endian XRGB1555 and RGB565 formats
  drm/format-helper: Fix endianness in drm_fb_*_to_*() conversion
    helpers
  drm/gud: Fix endianness in gud_xrgb8888_to_color() helper

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
