Subject: [PATCH 02/19] staging: wfx: reduce hold duration of cfg80211_bss
Date: Fri, 10 Apr 2020 15:32:22 +0200	[thread overview]
Message-ID: <20200410133239.438347-3-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200410133239.438347-1-Jerome.Pouiller@silabs.com>

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Pointer to cfg80211_bss is held during all duration of wfx_do_join. But,
it is not necessary, We can release it far earlier.
