From 09779276f1baea08985e08587319c8fed806b020 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Wed, 15 Jan 2020 13:54:14 +0000 Subject: [PATCH] staging: wfx: simplify hif_start() usage MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The structure hif_req_start come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_start() is too dumb. It should pack data with hardware representation instead of leaving all work to the caller.
