But good if you agree with that. IMHO just "sdm845-blueline" would be the most simple. I don't see the point of having a directory structure when there are not that many directories really.

Very good, thanks. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
