Since c32569e358ad ("regulator: Use of_node_name_eq for node name
comparisons") Vivien reported the mc13892-regulator complaining about
not being able to find regulators.
This is because prior to that commit we used of_node_cmp() to compare
the regulator array passed from mc13892_regulators down to
mc13xxx_parse_regulators_dt() and they are all defined in uppercase
letters by the MC13892_*_DEFINE* macros, whereas they are defined as
lowercase in the DTS.
Fix this by use strncasecmp() since that makes sure the comparison is
case insensitive like what of_node_cmp() did.
