mediatek: mt76: eeprom: fix missing of_node_put() in mt76_find_power_limits_node()

2022-08-17T12:41:04Z

[ Upstream commit 3bd53ea02d77917c2314ec7be9e2d05be22f87d3 ] We should use of_node_put() for the reference 'np' returned by of_get_child_by_name() which will increase the refcount.

mt76: mt7615: fix throughput regression on DFS channels

2022-08-17T12:41:03Z

[ Upstream commit aac86cebb4a09e3fa2c07589f79f7d0e07e8c9a4 ] For some reason, mt7615 reacts badly to repeatedly enabling/disabling the radar detector without also switching the channel. This results in very bad throughput on DFS channels, because hw->conf.radar_enabled can get toggled a few times after CAC ends. Fix this by always leaving the DFS detector enabled on DFS channels and instead suppress unwanted detection events.
