Subject: [PATCH 1/4] clk: milbeaut:  Don't reference clk_init_data after registration
Date: Thu, 15 Aug 2019 09:00:17 -0700
Message-ID: <20190815160020.183334-2-sboyd@kernel.org> (raw)
In-Reply-To: <20190815160020.183334-1-sboyd@kernel.org>

A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer
exceptions.
