PATCH (take 3) for adm1026.c, kernel 2.6.10-bk14

[Justin Thiessen <jthiessen@penguincomputing.com>]

Ok, take 3 on the adm1026 patch.

In this patch:

(1) Code has been added which ensures that the fan divisor registers are 
    properly read into the data structure before fan minimum speeds are 
    determined.  This prevents a possible divide by zero error.  The line 
    which reads the hardware default fan divisor values has been reformatted 
    as suggested by Andreas Dilger to make the intent of the statement clearer.

(2) In a similar spirit, an unecessary carriage return from a "dev_dbg" 
    statement in the adm1026_print_gpio() function has been elminated,
    shortening the statement to a single line and making the code easier
    to read.
