We cannot build the cec driver when the RC core is a module
and cec is built-in:

drivers/staging/built-in.o: In function `cec_allocate_adapter':
:(.text+0x134): undefined reference to `rc_allocate_device'
drivers/staging/built-in.o: In function `cec_register_adapter':
:(.text+0x304): undefined reference to `rc_register_device'

This adds an explicit dependency to avoid this case. We still
allow building when CONFIG_RC_CORE is disabled completely,
as the driver has checks for this case itself.

I originally submitted this on June 29, but it may have gotten
lost as out of the three patch series, one patch got replaced
and another patch got applied, but nothing happened on this one.

This makes no sense: the rc_allocate_device and rc_register_device
are under:

#if IS_REACHABLE(CONFIG_RC_CORE)

So it shouldn't be enabled at all, should it?

My mistake, I forgot to remove my patch from the backlog after
you added 5bb2399a4fe4 ("[media] cec: fix Kconfig dependency
problems"), and I saw that it's still marked as "new" in
patchwork with no reply.

I'll drop the patch from my local series and won't submit it again,
sorry for the mixup.
