[media] cec-notifier.h: handle unreachable CONFIG_CEC_CORE
Fix a link error in this specific combination of config options: CONFIG_MEDIA_CEC_SUPPORT=y CONFIG_CEC_CORE=m CONFIG_MEDIA_CEC_NOTIFIER=y CONFIG_VIDEO_STI_HDMI_CEC=m CONFIG_DRM_STI=y drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_remove': sti_hdmi.c:(.text.sti_hdmi_remove+0x10): undefined reference to `cec_notifier_set_phys_addr' sti_hdmi.c:(.text.sti_hdmi_remove+0x34): undefined reference to `cec_notifier_put' drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_connector_get_modes': sti_hdmi.c:(.text.sti_hdmi_connector_get_modes+0x4a): undefined reference to `cec_notifier_set_phys_addr_from_edid' drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_probe': sti_hdmi.c:(.text.sti_hdmi_probe+0x204): undefined reference to `cec_notifier_get' drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_connector_detect': sti_hdmi.c:(.text.sti_hdmi_connector_detect+0x36): undefined reference to `cec_notifier_set_phys_addr' drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_disable': sti_hdmi.c:(.text.sti_hdmi_disable+0xc0): undefined reference to `cec_notifier_set_phys_addr' The version below seems to work, though I don't particularly like the IS_REACHABLE() addition since that can be confusing to users.
