Research direction
The build error points to drivers/net/ethernet/mt7621-vendor/mtk_hnat/hnat_mcast.c:244, in hnat_mcast_netlink_open, after commit 3e55a98. Read that call and the bind function's expected argument type, then compare the relevant socket address declarations. Done when the Xiaomi AC2100 MT7621 build passes this compilation step without the incompatible pointer type error.
