Subject: [PATCH] [media] sti: hdmi: improve MEDIA_CEC_NOTIFIER dependency
Date: Wed, 19 Apr 2017 18:59:23 +0200 [thread overview]
Message-ID: <20170419165936.2836426-1-arnd@arndb.de> (raw)
When the media subsystem is built as a loadable module, a built-in
DRM driver cannot use the cec notifiers:
drivers/gpu/drm/sti/sti_hdmi.o: In function `sti_hdmi_remove':
sti_hdmi.c:(.text.sti_hdmi_remove+0x28): undefined reference to `cec_notifier_set_phys_addr'
sti_hdmi.c:(.text.sti_hdmi_remove+0x50): 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+0x84): 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+0x1a8): 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+0x68): 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+0xec): undefined reference to `cec_notifier_set_phys_addr'
This adds a Kconfig dependency to enforce the HDMI driver to also
be a loadable module in this case.
Fixes: bca55958ea87 ("[media] sti: hdmi: add CEC notifier support")
