Subject: [PATCH 8/9] phy: ti: am654-serdes: Don't reference clk_init_data after registration
Date: Wed, 31 Jul 2019 12:35:16 -0700 [thread overview]
Message-ID: <20190731193517.237136-9-sboyd@kernel.org> (raw)
In-Reply-To: <20190731193517.237136-1-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.
