You might want to remove these instead, and use the .editorconfig [1]
already present at src/gallium/drivers/freedreno/.editorconfig
This is much easier to maintain than per-files settings ;)

The website [1] has a link for a plugin for Emacs since it appears to
lack native support, but if you're ok with installing a plugin, this
should be a good solution for you :)
