+Subject: [PATCH] wifi: mt76: mt76x02: fix MT76x0 external LNA gain handling
+
+On MT76x0, LNA gain should be applied for both external and internal LNA.
+On MT76x2, LNA gain should be treated as 0 for external LNA.
+Move the LNA type based logic to mt76x2 in order to fix mt76x0.
+
+Fixes: 2daa67588f34 ("mt76x0: unify lna_gain parsing")
