From 42a31d4410a8be76c39fe47c6b280bfc0eca3e42 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 22 Mar 2024 16:05:31 +0800 Subject: [PATCH] firmware: arm_scmi: Log the perf domain names in the error paths Currently, the performance domain names are not logged whenever any error occurs when processing the OPPs by adding to local data structures or to the OPP library. It would be easier to locate the problem if domain name is printed out. So let us add the performance domain names to the other information logged already in the error paths.
