From 68d215d907b1512a8089f47a9d47d02a9a3b179e Mon Sep 17 00:00:00 2001 From: Rajan Vaja Date: Fri, 10 Aug 2018 01:45:33 -0700 Subject: [PATCH] dm: core: Move "/clock" node scan into function Create separate function for scanning node by path and move "/clock" node scan code into that function. This will be usable if scanning of more node is required.
