Subject: [PATCH 06/11] staging: wfx: fix endianness of hif API
From: Jérôme Pouiller <jerome.pouiller@...abs.com>
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.
Signed-off-by: Jérôme Pouiller <jerome.pouiller@...abs.com>
