Hi all,

After merging the sound-asoc-fixes tree, today's linux-next build
(x86_64 allmodconfig) produced these warnings:

Presumably introduced by commit

   82cb71d68c22 ("ASoC: SOF: Intel: add build support for SoundWire")

There is a companion patch 1eb629363aa35 ("ASoC: SOF: Intel: hda: import 
SOUNDWIRE_INIT namespace") that does the import, not sure what causes 
the warning?
