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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/5969a3df8361a0e20379a308c2313d3e263123de","tags":[]},{"url":"https://git.kernel.org/stable/c/b2702908ee23ef31bfcf241a2e07ace0eb76bd71","tags":[]},{"url":"https://git.kernel.org/stable/c/bfce0f324efaa605e606cbb3f0bdb8fe5c910c11","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
