I guess you only wanted to remove re-declaration part. Assigning the
value returned by this function doesnt seem to happen before.
drc_index is assigned at the top of this large routine with :
drc_index = rtas_ld(wa_addr, 0);
drc = spapr_drc_by_index(drc_index);
So, the extra local variable 'drc_index' is simply redundant because
there are no reason for it to change. The drc object is the same AFAICT.
Correct ? I should have explained that better in the commit log.
Okay, since both routines were implemented differently, I wasn't sure about
the impact of reassignment. Better commit log is always welcome.
