Eduard,
I suspect that this is some bug on the out-of-tree build. In order to test it,
I've tried to reproduce what I think you did.
So, I ran the following procedures over the devel branch on my -git tree:
make allmodconfig (to select everything as 'm')
I manually unselect all drivers at the tree, keeping only CX88 and submodules.
All CX88 submodules as "M".
I've repeated the procedure, this time starting with make allyesconfig.
On both cases, I got those configs:
CONFIG_VIDEO_CX88=m
CONFIG_VIDEO_CX88_ALSA=m
CONFIG_VIDEO_CX88_BLACKBIRD=m
CONFIG_VIDEO_CX88_DVB=m
CONFIG_VIDEO_CX88_MPEG=m
CONFIG_VIDEO_CX88_VP3054=m
My -git tree were updated up to this changeset:

V4L/DVB (10411): s5h1409: Perform s5h1409 soft reset after tuning
I tried also reproduce the bug you've mentioned at the v4l-dvb tree, but
unfortunately, I couldn't (the .config file is attached). I got exactly the
same result as compiling in-kernel.
Could you please send us your buggy .config?
Cheers,
Mauro
