This is wrong.

First you assign "ccflags-y" the value -Idrivers/media/video
And in next line you assign it a new value - loosing the old value.

It should lok like this:

> +ccflags-y += -Idrivers/media/common/tuners
> +ccflags-y += -Idrivers/media/dvb/dvb-core

In this way you append to the variable.

You said in another mil that it builds.
This tells me that either some of the assignments are not needes - or you just loose
something that you are not aware of.

Please go through all your patches and fix it up - I saw the above
bug in the two patches I looked at.
