From 8b7912f4cb6c29a1223ca7f2472bf12c44cc285e Mon Sep 17 00:00:00 2001 From: Pavankumar Kondeti Date: Thu, 30 Sep 2021 15:39:08 +0530 Subject: opp: Fix required-opps phandle array count check The 'required-opps' property is optional. So of_count_phandle_with_args() can return -ENOENT when queried for required-opps. Handle this case.
