Subject: [PATCH] mt76: mt7921: introduce mt7921_mcu_set_beacon_filter utility routine
Date:   Mon,  9 Aug 2021 12:37:22 +0200
Message-Id: <838dac6060bd2659ab6997e0a930325283d1b7c1.1628505383.git.lorenzo@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Introduce mt7921_mcu_set_beacon_filter utility routine in order to
remove duplicated code for hw beacon filtering.
Move mt7921_pm_interface_iter in debugfs since it is just used there.
Make the following routine static:
- mt7921_pm_interface_iter
- mt7921_mcu_uni_bss_bcnft
- mt7921_mcu_set_bss_pm
