From: Shiji Yang <yangshiji66@xxxxxxxxxxx> [ Upstream commit 50da74e1e8b682853d1e07fc8bbe3a0774ae5e09 ] 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.
