of: use kbasename instead of open coding
Several places in DT code open code the equivalent of kbasename. Replace them. The behavior for root nodes in node_name_cmp will be slightly different. Instead of comparing "/", "" will be compared. The comparison will be the same. Reviewed-by: Andy Shevchenko <andy.shevhchenko@gmail.com> Signed-off-by: Rob Herring <robh@kernel.org>
