Subject[PATCH v2 10/65] staging: wfx: use specialized structs for HIF arguments
Date
From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Most of the commands that are sent to device should take struct in
argument. In the current code, when this struct is binary compatible
with a __le32, the driver use a __le32. This behavior is error prone.
This patch fixes that and uses the specialized structs instead.
