From 9ed8b0d0f27cf7ba183d8e8e7c5cc47afb7a00ae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Pouiller?= <jerome.pouiller@silabs.com> Date: Wed, 15 Jan 2020 13:54:12 +0000 Subject: [PATCH] staging: wfx: simplify hif_set_rcpi_rssi_threshold() usage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The structure hif_mib_rcpi_rssi_threshold come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_set_rcpi_rssi_threshold() is dumb. It should pack data using the hardware representation instead of leaving all work to the caller.
