4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lorenzo Bianconi <lorenzo.bianconi@xxxxxxxxxx>
commit 473f0a763d2c7cd68a6dedf51e7d81e8f58f78ac upstream.
According to vendor sdk, vco calibration has to be executed
for each channel configuration whereas mcu calibration has to be
performed during channel scanning. This patch fixes the mt76x0
monitor mode issue since in that configuration vco calibration
was never executed
