Thanks, I agree with your opinion, but other Makefiles in drivers/media use same hack. I don't know other way to include headers of demodulators and tuners... Do you have any good ideas?

For clarification, Bad: ccflags-y += -Idrivers/media/dvb-frontends/ ccflags-y += -Idrivers/media/tuners/ Good: ccflags-y += -I$(srctree)/drivers/media/dvb-frontends/ ccflags-y += -I$(srctree)/drivers/media/tuners/ I want to fix this tree-wide, then remove the 'addtree' from scripts/Kbuild.include but I have not been able to find time for that. This is a new file, so just suggested to add '$(srctree)/' If you want to know the context: https://patchwork.kernel.org/patch/9632347/
