    dm: convert ffs to __ffs · a3d939ae
    Mikulas Patocka authored
    ffs counts bit starting with 1 (for the least significant bit), __ffs
    counts bits starting with 0. This patch changes various occurrences of ffs
    to __ffs and removes subtraction of 1 from the result.
    
    Note that __ffs (unlike ffs) is not defined when called with zero
    argument, but it is not called with zero argument in any of these cases.
