I prefer the drivers to NOT use include ccflags in the kernel as it breaks the build when trying to build just a subdirectory. If/when this code ever gets out of staging, then the include lines can be fixed up to point to the correct location of wherever the files move to. So I like this patch, but as I couldn't take the first one, this and the rest did not apply so I'll wait for them to be resubmitted. thanks, greg k-h
