From: Stephen Boyd <sb...@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.
