From 95e6b1fa3311c8a7b151d38540695409048d1495 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 1 Jun 2017 18:00:00 -0500 Subject: [PATCH] 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.
