With CONFIG_SND_SOC_SOF_COMPRESS=m, the compression code is
not built into a the main SOF driver when that is built-in:

x86_64-linux-ld: sound/soc/sof/ipc.o: in function `ipc_stream_message':
ipc.c:(.text+0x5a2): undefined reference to `snd_sof_compr_fragment_elapsed'
x86_64-linux-ld: sound/soc/sof/topology.o: in function `sof_dai_load':
topology.c:(.text+0x32d1): undefined reference to `snd_sof_compr_init_elapsed_work'
x86_64-linux-ld: topology.c:(.text+0x32e1): undefined reference to `snd_sof_compr_init_elapsed_work'

Make this a 'bool' symbol so it just decides whether the
code gets built at all.

It's Monday morning and my memory is still foggy but I think we fixed
this problem with https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fthesofproject%2Flinux%2Fpull%2F3180&amp;data=04%7C01%7Cdaniel.baluta%40nxp.com%7C25ac869cfd1040f1be1708d9a2bd3460%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C637719755777370422%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=E4K2DPkpLX2SgVJ1K99Qs3uz7l7mS96gIzYlJw9akbg%3D&amp;reserved=0,
where we changed the Kconfigs for i.MX. We haven't sent this update
upstream for some reason.

Arnd, can you share the configuration that breaks with the existing
upstream code, I can check if the problem still exists.


Maybe someone forgot :) to send https://github.com/thesofproject/linux/pull/3180/commits/7122edc88d13db8ba835bdb20f7444ae535f9ffa upstream.

I think that's me.

Arnd can you run your scripts with https://github.com/thesofproject/linux/pull/3180/commits/7122edc88d13db8ba835bdb20f7444ae535f9ffa. I also attached the patch

if it's easier to apply.
