FYI, there's a new build breakage here:

 drivers/built-in.o: In function `cx231xx_audio_fini':
 cx231xx-audio.c:(.text+0xd4e43): undefined reference to `snd_card_free'
 drivers/built-in.o: In function `cx231xx_audio_isocirq':
 cx231xx-audio.c:(.text+0xd4fb7): undefined reference to `snd_pcm_link_rwlock'
 cx231xx-audio.c:(.text+0xd5021): undefined reference to `snd_pcm_link_rwlock'
 cx231xx-audio.c:(.text+0xd50bb): undefined reference to `snd_pcm_period_elapsed'
 drivers/built-in.o: In function `snd_cx231xx_capture_open':

config attached.

I suspect the key problem is that sound is modular while cx231xx is 
built-in:

 CONFIG_SOUND=m
 CONFIG_VIDEO_CX231XX=y
 CONFIG_VIDEO_CX231XX_ALSA=y

This has a similar pattern to past build breakages in this area.
