The work can subsequently\ndereference the devm-allocated mmci_host after it has been released.\n\nMask the controller interrupts and disable the delayed work during\nremoval. This drains any queued instance and stops an IRQ handler that\nis still in progress from queueing the work again once it has been\ndisabled.\n\nThis issue was found by an in-house static analysis tool."
