Indeed, but it is effectively Broadcom's fault for not providing a git tree for the customer to pull from in order to preserve the original authorship, if what was distributed is a tarball of changes against a vanilla kernel (which is likely to be the case), then all author attributions are lost. Not suggesting you change how you deliver code to customers, we have the same issue in the STB/CM group, except maybe customers care less about upstreaming so we can do it ourselves at our own pace and using our own attributions. > Point a) and b) are not met in > Developer's Certificate of Origin while point c) is being attempted > (without a or b being certified). I would think that point a) and b) are met by the very fact that the Cygnus kernel port is GPLv2 code, being a derivative work of the Linux kernel, and that should be enough. This is kind of well established things, this has happened for many Broadcom product lines unfortunately because not everyone is active like you in getting things upstreamed. Those contributions were still entirely valid and acceptable for the kernel community.
