From: Stephen Boyd <sb...@kernel.org> [ Upstream commit f6c90df8e7e33c3dc33d4d7471bc42c232b0510e ]
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.
