[BUG] Compile error with CONFIG_SND_OMAP_SOC_OMAP4_HDMI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi list,

Trying to compile 3.3-rc6 with the following option combination fails:

CONFIG_SND_OMAP_SOC_OMAP4_HDMI=m
CONFIG_SND_OMAP_SOC_HDMI=m
CONFIG_OMAP2_DSS=y

drivers/built-in.o: In function `omapdss_hdmihw_remove':
/home/abuild/rpmbuild/BUILD/kernel-omap2plus-3.3.rc6/linux-3.3-rc6/drivers/video/omap2/dss/hdmi.c:879: undefined reference to `snd_soc_unregister_codec'
drivers/built-in.o: In function `omapdss_hdmihw_probe':
/home/abuild/rpmbuild/BUILD/kernel-omap2plus-3.3.rc6/linux-3.3-rc6/drivers/video/omap2/dss/hdmi.c:863: undefined reference to `snd_soc_register_codec'

However, we do want to have DSS compiled into the kernel to ensure that graphics are available, but since audio is not quite as crucial for debugging, that one should live as a module.

According to Takashi, it shouldn't be all that hard to split the HDMI audio code from dss/hdmi.c, but I'm currently lacking the time to do so. If anyone's interested in picking it up, I'd very much appreciate it!


Thanks a lot,

Alex
