Subject: [PATCH] ASoC: SOF: Makefile: Fix randconfig sof-client build when SND_SOC_SOF=y

From: Peter Ujfalusi <peter.ujfalusi@...il.com>

Intel's kernel test robot found the following randconfig combination:
SND_SOC_SOF=y
SND_SOC_SOF_CLIENT=m

In this the sof-client object is not going to be built into the snd-sof.o
and we will have undefined references to the sof-client functions.

Fixes: 6955d9512d0e ("ASoC: SOF: Introduce IPC SOF client support")
Reported-by: kernel test robot <lkp@...el.com>

Hi Mark, Pierre,

When the client support was added we did some permutation tests (at least I did)
but missed this combination.
It is a valid one for sure and the proper fix is via the Makefile.

Sorry for mising this

Regards,
Peter
