Subject: [PATCH] mt76: mt7615: add mt7615_mutex_acquire/release in mt7615_sta_set_decap_offload
Date:   Mon, 25 Jul 2022 10:26:40 +0200
Message-Id: <8f71863b5d10cad0b1b3e3c653c40d8b2a787102.1658737542.git.lorenzo@kernel.org>

Similar to mt7921 driver, introduce mt7615_mutex_acquire/release in
mt7615_sta_set_decap_offload in order to avoid sending mcu commands
while the device is in low-power state.

Fixes: d4b98c63d7a77 ("mt76: mt7615: add support for rx decapsulation offload")
