Would that be worth doing? Yes, please. It would be nice to cleanup linux-firmware.git top level directory. But what about this: * convert iwlwifi to first use _all_ files under intel/ and then as a fallback top level directory * move existing iwlwifi firmware files to intel/ but create symlinks from the old location to the new one (using 'Link:' in WHENCE) * add new files only to intel/ directory * after few (4?) years remove the symlinks from linux-firmware and the fallback from iwlwifi This should ensure backwards compatibility, right? -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
