The patch bellow should fix the issue. The bad thing is that, if you deselect
IR_CORE, several drivers like bttv would be deselected too.
So, a further action would be to work on some solution for it.
The first alternative would be to write some stubs at ir-core.h to allow
compiling the V4L/DVB drivers without IR support, removing the "depends on"
for those drivers. The bad thing is that the subsystem headers will have some
#ifs there.
Another alternative would be to do this inside the drivers and/or drivers headers.
In general, at driver level, there are just one or two functions called in order
to activate/deactivate the remote controllers. So, IMHO, this would provide a cleaner
way.
I'll likely do some patches using the second alternative and see how it will look like.
Cheers,
Mauro.

Those breakages seem to be caused by two bad things at IR_CORE Kconfig:
1) cx23885 is using select for IR_CORE;
2) the dvb-usb and sms dependency for IR_CORE were missing.
While here, allow users to un-select IR.
