OK, sorry, I didn't spot this last time around - but these two lines
are now present for both sides of the conditional, so should be moved
outside. Which (I think) would turn it into
mDwEmmcCommand = Cmd;
mDwEmmcArgument = Argument;
if (!IsPendingReadCommand (Cmd) && !IsPendingWriteCommand (Cmd)) {
Status = SendCommand (Cmd, Argument);
}

Space after if. Space after IsPendingWriteCommand.
