The variable 'max_support_idx, min_support_idx, pm_lock_idx"
are never used, so remove the unused variable.

Should be tab.

  ^^^^^^^^ ???

Same.

Same.

> -       unsigned int    max_support_idx;

Same.

> -       unsigned int    min_support_idx;

Same.

Hmm...many white spaces are used at places that tab should be used...it
seems that e-mail client had some problems when you're sending...

Note, you can see following with checkpatch.

WARNING: please, no spaces at the start of a line

Basically, this whole series' contents look good to me, but need to re-send
