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\nvisconti_clk_register_gate() 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.","state":0,"publishedAt":"2026-09-17T16:06:25.91+00:00","modifiedAt":"2026-10-19T08:58:20.601+00:00","affected":[{"ecosystem":"Vendor
