DENG Qingfang 718e97c5c8 ramips: mt7530 swconfig: fix race condition in register access ... [ Upstream commit f99c9cd9c4 ] The mt7530_{r,w}32 operation over MDIO uses 3 mdiobus operations and does not hold a lock, which causes a race condition when multiple threads try to access a register, they may get unexpected results. To avoid this, handle the MDIO lock manually, and use the unlocked __mdiobus_{read,write} in the critical section. This fixes the "Ghost VLAN" artifact[1] in MT7530/7621 when the VLAN operation and the swconfig LED link status poll race between each other.
