From 020d86fc0df8b865f6dc168d88a7c2dccabd0a9e Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Thu, 12 Aug 2021 16:57:20 +0530 Subject: opp: Don't print an error if required-opps is missing The 'required-opps' property is considered optional, hence remove the pr_err() in of_parse_required_opp() when we find the property is missing. While at it, also fix the return value of of_get_required_opp_performance_state() when of_parse_required_opp() fails, return a -ENODEV instead of the -EINVAL.
