The warning is probably caused by:
staging: wfx: fix endianness of hif API
The chip expects little endian in all structs it sends/receives. This
patch fixes the hif API to reflect this fact. Sparse should now report
meaningful errors.
And indeed, Sparse now reports ton of errors :). I am currently working
on these warnings. I hope to provide a patch soon.
