That work is only cancelled on the suspend\npath (mmc_sdio_suspend()), not on the remove/free path, so a worker armed\njust before the controller freed its IRQ can run after\nmmc_host_classdev_release() has freed the host and dereference it through\ncontainer_of().\n\nCancel host->sdio_irq_work in mmc_free_host(), like the existing\nhost->detect drain added by
