has been resolved:\n\nmmc: sdio: fix possible resource leaks in some error paths\n\nIf sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can\nnot release the resources, because the sdio function is not presented\nin these two cases, it won't call of_node_put() or put_device().\n\nTo fix these leaks, make sdio_func_present() only control whether\ndevice_del() needs to be called or not, then always call of_node_put()\nand put_device().\n\nIn error case in sdio_init_func(), the reference of 'card->dev' is\nnot get, to avoid redundant put in sdio_free_func_cis(), move the\nget_device() to sdio_alloc_func() and put_device() to sdio_release_func(),\nit can keep the get/put function be balanced.\n\nWithout this patch, while doing fault inject test, it can get the\nfollowing leak reports, after this fix, the leak is gone.\n\nunreferenced object 0xffff888112514000 (size 2048):\n comm \"kworker/3:2\", pid 65, jiffies 4294741614 (age 124.774s)\n hex dump
