   3 Subject: [PATCH] wifi: rt2x00: correct wrong BBP register in RxDCOC
   4  calibration
   5
   6 Refer to Mediatek vendor driver RxDCOC_Calibration() function, when
   7 performing gainfreeze calibration, we should write register 140
   8 instead of 141. This fix can reduce the total calibration time from
   9 6 seconds to 1 second.
