[PATCH v7 2/6] [media] cec-notifier.h: Prevent build warnings using forward declaration

From: Jose Abreu
Date: Fri Jul 07 2017 - 07:09:10 EST


When CONFIC_CEC_NOTIFIER is not set and we only include cec-notifier.h
we can get build warnings like these ones:

"warning: âstruct cec_notifierâ declared inside parameter list will
not be visible outside of this definition or declaration"

Prevent these warnings by using forward declaration of notifier
structure.
