Subject: [PATCH AUTOSEL 5.2 29/70] clk: meson: axg-audio: Don't reference clk_init_data after registration
Date: Tue, 24 Sep 2019 12:45:08 -0400 [thread overview]
Message-ID: <20190924164549.27058-29-sashal@kernel.org> (raw)
In-Reply-To: <20190924164549.27058-1-sashal@kernel.org>
From: Stephen Boyd <sboyd@kernel.org>
[ Upstream commit 1610dd79d0f6202c5c1a91122255fa598679c13a ]
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.
