From: Stephen Boyd <sboyd@xxxxxxxxxx> [ Upstream commit cf9ec1fc6d7cceb73e7f1efd079d2eae173fdf57 ] 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.
