I cannot reproduce the same sparse errors.

CHECK sound/soc/codecs/cros_ec_codec.c
CC [M] sound/soc/codecs/cros_ec_codec.o
It did not generate the same message as 0day reported.
One difference would be the sparse version (it is from "apt install"
in my environment):
$ sparse --version
0.6.0 (Debian: 0.6.0-3)
On the other hand, 0day used "v0.6.1-rc1-42-g38eda53-dirty".
Guenter, what we could do in the case? Do you have any idea?
