Subject: [PATCH 4/9] mac80211: Add missing annotation for brcms_rfkill_set_hw_state()
Date: Sat, 11 Apr 2020 01:19:28 +0100 [thread overview]
Message-ID: <20200411001933.10072-5-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200411001933.10072-1-jbi.octave@gmail.com>
Sparse reports a warning at brcms_rfkill_set_hw_state()
warning: context imbalance in brcms_rfkill_set_hw_state()
- unexpected unlock
The root cause is the missing annotation at brcms_rfkill_set_hw_state()
Add the missing __must_hold(&wl->lock) annotation
