Subject: [PATCH 2/2] [media] cec: add RC_CORE dependency

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.

Signed-off-by: Arnd Bergmann <arnd@...db.de>

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.
