[ Upstream commit a767957e7a83f9e742be196aa52a48de8ac5a7e4 ]
In ptp_ocp_sma_fb_init(), the code mistakenly used bp->sma[1] instead of bp->sma[i] inside a for-loop, which caused only SMA[1] to have its DIRECTION_CAN_CHANGE capability cleared. This led to inconsistent capability flags across SMA pins.
