From f050f3dac6686903f001862cc7b67bd2dcaeaea1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Wed, 15 Jan 2020 13:54:21 +0000 Subject: [PATCH] staging: wfx: drop wdev->output_power MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit mac80211 and the device are both able to control tx power per vif. But, the current code retrieve tx power from wfx_config(). So, it does not allow to setup the tx power independently for each vif. Driver just has to rely on bss_conf->txpower to get the correct information. In add, it is no more necessary to protect access to wdev->output_power with scan_lock.
