[PATCH 06/11] staging: wfx: fix endianness of hif API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx>

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.
