However,\nnot initializing all members may cause subtle issues, which are only\nexposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is\nenabled.\n\naml_spisg_clk_init() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter in uninitialized, and\nthus may cause a crash.\n\nMake sure all members are fully initialized, to fix such bugs, and to\navoid future breakage when converting drivers to a different method for\nspecifying the parents."
