This switches us over to Mesa's code style [1], normalizing us within the tree. The results aren't perfect, but they bring us a hell of a lot closer to the rest of the tree. Panfrost doesn't feel so foreign relative to Mesa with this, which I think (in retrospect after a bunch of years of being "different") is the right call. I skipped PanVK because that's paused right now. find panfrost/ -type f -name '*.h' | grep -v vulkan | xargs clang-format -i; find panfrost/ -type f -name '*.c' | grep -v vulkan | xargs clang-format -i; clang-format -i gallium/drivers/panfrost/*.c gallium/drivers/panfrost/*.h ; find panfrost/ -type f -name '*.cpp' | grep -v vulkan | xargs clang-format -i [1] https://docs.mesa3d.org/codingstyle.html Signed-off-by: Alyssa Rosenzweig <alyssa@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/20425>
