Care to explain why the error is happening?

Not sure if this last line is correct. The kbuild report says this
error starts to happen with:
commit: 8cfc8ddc99df9509a46043b14af81f5c6a223eab pstore: add lzo/lz4
compression support

on a x86_64 randconfig.

Also, why only SND_SOC_FSL_SPDIF needs to have BITREVERSE selected?
