+
+Hence remove errornous line 5281 to make the driver actually
+execute the correct initialization routine for MT7620 chips.
+
+As it was requested by Stanislaw Gruszka remove setting values of
+MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
+power-safe mode (which is disabled), hence we can drop setting it.
+TX_PIN_CFG is set correctly in other functions, and as setting this
+value breaks some devices, rather don't set it here during init, but
+only modify it later on.
+
+Fixes: 41977e86c984 ("rt2x00: add support for MT7620")
