The memory that allocated in mmc_alloc_host() is leaked.\n2. In the remove() path, mmc_remove_host() will be called to\n   delete device, but it's not added yet, it will lead a kernel\n   crash because of null-ptr-deref in device_del().\n\nSo fix this by checking the return value and calling mmc_free_host()\nin the error path."
