[alsa-devel] [PATCH 2/2] ASoC: SOF: core: fix undefined nocodec reference

[Pierre-Louis Bossart]

The existing code mistakenly uses IS_ENABLED in C code instead of as
in conditional compilation, leading to the following error:

ld: sound/soc/sof/core.o: in function `sof_machine_check':
sound/soc/sof/core.c:279: undefined reference to `sof_nocodec_setup'

Fix by using #if !IS_ENABLED()
