However, mc->root_mc_bus_dev is already freed in\nfsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io\ntriggers KASAN use-after-free. To avoid the use-after-free, keep the\nreference to mc->root_mc_bus_dev->mc_io in a local variable and pass to\nfsl_destroy_mc_io().\n\nThis patch needs rework to apply to kernels older than v5.15."
