Subject: [PATCH v7 25/28] clk: Zero the clk_rate_request structure
Date: Fri, 15 Jul 2022 18:00:11 +0200	[thread overview]
Message-ID: <20220715160014.2623107-26-maxime@cerno.tech> (raw)
In-Reply-To: <20220715160014.2623107-1-maxime@cerno.tech>

In order to make sure we don't carry anything over from an already
existing clk_rate_request pointer we would pass to
clk_core_init_rate_req(), let's zero the entire structure before
initializing it.
