The work is embedded in a devm-allocated mmc_hsq, but\nis never cancelled during driver removal. Work still pending at unbind\ncan therefore run after the devm allocation has been released and\ndereference hsq->mmc and hsq->mrq.\n\nUse devm_work_autocancel() to cancel and drain retry_work before the devm\nallocation is released. By the time devres cleanup begins,\nmmc_remove_host() has already stopped the host, so no new requests can\narm the work.\n\nThis issue was found by an in-house static analysis tool.","state":0,"publishedAt":"2026-10-06T08:44:48.498+00:00","modifiedAt":"2026-10-19T09:15:43.105+00:00","affected":[{"ecosystem":"Vendor
