From 43bc4cfef2b18fad0141af7aff7703b5081aa4a5 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Tue, 7 Mar 2023 14:29:28 +0100 Subject: [PATCH] clk: Print an info line before disabling unused clocks [ Upstream commit 12ca59b91d04df32e41be5a52f0cabba912c11de ] Currently, the regulator framework informs us before calling into their unused cleanup paths, which eases at least some debugging. The same could be beneficial for clocks, so that random shutdowns shortly after most initcalls are done can be less of a guess. Add a pr_info before disabling unused clocks to do so.
