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