If the problem doesn't manifest itself during in-kernel build, I believe
it must be with either v4l/Makefile or one of the scripts in scripts/*
As a matter of fact, I found out that commenting out
"disable_config('DVB_FE_CUSTOMISE');" in scripts/make_kconfig.pl line
588 and doing a "make distclean; make all" will cause all the undefined
config variables to be set to 'm' and the missing modules to be built
again.
Why is this disable_config() in there anyway? There is no corresponding
disable_config("MEDIA_TUNER_CUSTOMIZE"), which is used in the same way
in linux/drivers/media/common/tuners/Kconfig to hide a menu.
The only (aesthetic?) difference is that DVB_FE_CUSTOMISE ends up set to
'y' in the generated config (as has always been the case with
MEDIA_TUNER_CUSTOMIZE by the way), but that doesn't matter much at
module build time. A user should not configure _after_ building modules
anyway, so the menu showing up doesn't really matter.
Also note yet another -IZE / -ISE spelling issue :-)
Kind regards,
Alain
