Subject: [PATCH AUTOSEL 4.19 14/42] mac80211: don't warn about CW params when not using them
Date: Fri,  2 Aug 2019 09:22:34 -0400
Message-ID: <20190802132302.13537-14-sashal@kernel.org> (raw)
In-Reply-To: <20190802132302.13537-1-sashal@kernel.org>

From: Brian Norris <briannorris@chromium.org>

[ Upstream commit d2b3fe42bc629c2d4002f652b3abdfb2e72991c7 ]

ieee80211_set_wmm_default() normally sets up the initial CW min/max for
each queue, except that it skips doing this if the driver doesn't
support ->conf_tx. We still end up calling drv_conf_tx() in some cases
(e.g., ieee80211_reconfig()), which also still won't do anything
useful...except it complains here about the invalid CW parameters.

Let's just skip the WARN if we weren't going to do anything useful with
the parameters.
