As of v4.6-rc6, I hit this error during randconfig.

LD init/built-in.o sound/built-in.o: In function `snd_byt_rt5640_mc_probe': /home/iida/Repo/linux-2.6/sound/soc/intel/boards/bytcr_rt5640.c:361: undefined reference to `sst_acpi_find_name_from_hid' make: *** [vmlinux] Error 1

Hi guys,

I'm seeing a bunch of those errors today on randconfig builds:

sound/built-in.o: In function `snd_byt_rt5640_mc_probe': bytcr_rt5640.c:(.text+0x1593b4): undefined reference to `sst_acpi_find_name_from_hid' make: *** [vmlinux] Error 1

ERROR: "sst_acpi_find_name_from_hid" [sound/soc/intel/boards/snd-soc-sst-bytcr-rt5640.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 make: *** Waiting for unfinished jobs....

Some of the failing configs attached.

I have 2 patches for this. I'll send them right away.
