From 9f7767226083d51c0674f1b71ac52daea6778b84 Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Tue, 2 Jul 2019 16:27:10 +0300 Subject: [PATCH] clk: Assert prepare_lock in clk_core_get_boundaries This function iterates the clk consumer list on clk_core so it must be called under prepare_lock. This is already done by all callers but add a lockdep assert to check anyway.
