Subject: [PATCH 14/65] staging: wfx: drop wdev->output_power
Date: Wed, 15 Jan 2020 12:12:27 +0000 [thread overview]
Message-ID: <20200115121041.10863-15-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200115121041.10863-1-Jerome.Pouiller@silabs.com>
From: Jérôme Pouiller <jerome.pouiller@silabs.com>
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.
