However, on driver\nremove/teardown, the generic chips are not automatically freed when the\nIRQ domain is removed because the domain flags do not include\nIRQ_DOMAIN_FLAG_DESTROY_GC.\n\nThis causes both the domain generic chips structure and the associated\ngeneric chips to be leaked. Additionally, the generic chips remain on\nthe global gc_list and may later be visited by generic IRQ chip suspend,\nresume, or shutdown callbacks after the GPIO bank has been removed,\npotentially resulting in a use-after-free and kernel crash.\n\nFix the resource leak by explicitly calling\nirq_domain_remove_generic_chips() before removing the IRQ domain in\nrockchip_gpio_remove().","state":0,"publishedAt":"2026-06-25T08:39:26.567+00:00","modifiedAt":"2026-10-21T12:42:17.298+00:00","affected":[{"ecosystem":"Vendor
