[lm-sensors] [PATCH] adm1026: fix setting fan_div

[Gabriele Gorla]

Thanks everyone for the feedback.

I resubmitted 2 bugfixes only patches:
1- to fix the div setting
2- stop rejecting div=1 since it is valid

I left the locking around the entire structure access as requested.

I can submit another patch to validate the input to 1,2,4,8 to be applied in the development 
kernels.

I am not sure if we reached an agreement on the internal representation of fan_div so I 
am leaving it alone for now.

thanks,
GG
