Nothing wrong with this, I just didn't had time to double check it myself and then forgotten about it.

Going to push it to drm-misc-next.

This patch tries to improve the display of the code listing on The Linux Kernel documentation website for dma-buf [1] .

Originally, it appears that it was attempting to escape the '*' character, but looks like it's not necessary (now), so we are seeing something like '*' on the webite.

This patch removes these unnecessary backslashes and adds syntax highlighting to improve the readability of the code listing.
