If an interruptarrives in that window:\n - mx3_gpio_irq_handler() calls generic_handle_domain_irq() with   port->domain still NULL. - mx2_gpio_irq_handler() walks mxc_gpio_ports, but the port has not   been added to the list yet.\nAdditionally, if any of the subsequent probe steps(gpio_generic_chip_init(), devm_gpiochip_add_data(),irq_domain_create_legacy(), or mxc_gpio_init_gc()) fail, the errorpaths never unregister the chained handler, leaving a dangling handlerthat points at freed memory.\nMove the handler installation after all its dependencies are ready andafter list_add_tail(), so the handler is never live while the datastructures it touches are incomplete, and is never installed if probefails.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99189https://git.kernel.org/stable/c/261802c14e1a3281987ea8f106701e5ed9652f68https://git.kernel.org/stable/c/6c1e035d881579a6e4ed1ce5feabb13d23e80a82https://git.kernel.org/stable/c/38d44f78f041ffe60c8e2443b99434a199e7541d#kernel
