Setting frequency to 0 is not enough, the clock explicitly has to be disabled. Otherwise voltage switching (which needs SDCLK to be quiet) fails for various cards. Because we now do the 'new_clock == 0' check right at the beginning, the indentation level of the rest of the code can be decreased a little.
